How to build static lib's

How to build static lib's

[Kevin Wright]

Hello,

I've been using cygwin for about a year and have 
always had some problems building static only 
versions of libraries such as glib and gtk+.

Here's the configure options I've tried:

./configure --disable-shared --disable-shm --disable-nls --no-recursion

However, I still end up building the .lo & subsequent .la files. 
I tried hacking the libtool files but that was useless because it gets
created during the configure process. The problem is that certain lib's
programs fail with messages such as:

gdk_imlib ERROR: Cannot load image: 
/usr/local/share/pixmaps/gnome-question.png
All fallbacks failed.

WARNING: previous dlopen of 
E:\usr\local\lib\libimlib-png.so wasn't correctly performed


Is there a way to make these libs truly static? 

I'm using gcc 2.95 and cygwin b20.1. Perhaps this is fixed in a 
newer snapshot of the cygwin1.dll but I am waiting for the 
complete installation package to be released.

TIA,

This problem is due to a bug in cygwin-b20, and is fixed in recent
snapshots. In most cases, it is quite harmless (unless you're creating
subprocesses using fork/exec, in which case odd things may happen).

You need to ask the GTK folks about it. --disable-shared should have
created static libs only, but for some packages, that is not an option.
It's not possible to tell what the problem is from just what you've 
posted, sorry.

Gtk+ and GNOME for MingW32 are available.  They are build as shared
libs (DLLs) I do not remember URL from where I downloaded them
couple of weeks ago.

The modified source code as well as  GTK+ and GNOME for
MINGW32 is at: It is compiled using egcs-1.1.2, as far I remember
from
the notes on URL.

For more information about the port or GLib, GTk+ and the GIMP to
native Windows, and pre-built binary packages, see
http://www.iki.fi/tml/gimp/win32/ or
http://www.gimp.org/~tml/gimp/win32/

You might refer to the stuff I have available at
http://www.iki.fi/tml/gimp/win32/ . It's just GLib and GTk+ (and the
GIMP), nothing directly GNOME-related, though. Also, there is a
desperate need for documentation how to use my precompiled DLLs when
building GTk+ programs. (It is a bit complex, as you must use
gcc-2.95, and remember to use the -mno-cygwin and -fnative-struct
flags, and patch the gcc setup to use msvcrt and not crtdll. Well,
actually I don't know if it's absolutely necessary to use msvcrt in
the client program even if the gtk, gdk and glib DLLs use it.)

Yes right.  that is what i was refering to.  Thought not directly
related to Gnome, but I found GTK+ and GDK+ ports very useful.

The GIMP is impressive, too. It did crashed on me with errors, once
in
a while when loading tiff.exe plug-ins.  It does crash if you
attempt to
open a tiff or jpeg file which is corrupted.

Does this mean that the old fork/exec problem that plagued cygwin-perl a
while back is fixed in recent snapshots? Not fixed? Partially fixed?

I don't think so.  I investigated this a while ago.  I looks like the problem
is due to the fork code loading the DLLs in the wrong order which causes the
DLLs in the child to be loaded in different locations than the parent.

Here is a snippet of the output from running configure:

checking for ld used by GCC... /bin/ld.exe
checking if the linker (/bin/ld.exe) is GNU ld... yes
checking for BSD-compatible nm... /bin/nm -B
checking whether ln -s works... yes
updating cache ./config.cache
loading cache ./config.cache within ltconfig
checking for object suffix... o
checking for executable suffix... .exe
checking for gcc option to produce PIC... none
checking if gcc supports -c -o file.o... yes
checking if gcc supports -c -o file.lo... yes
checking if gcc supports -fno-rtti -fno-exceptions ... yes
checking if gcc static flag -static works... -static
checking if the linker (/bin/ld.exe) is GNU ld... yes
checking whether the linker (/bin/ld.exe) supports shared libraries... yes
checking command to parse /bin/nm -B output... ok
checking how to hardcode library paths into programs... immediate
checking for /bin/ld.exe option to reload object files... -r
checking dynamic linker characteristics... Win32 ld.exe
checking if libtool supports shared libraries... yes
checking if package supports dlls... no
checking whether to build shared libraries... no
checking whether to build static libraries... yes

It seams that the configure script is broken because even though I specify
using no static libs, it still checks for whether libtool support shared
libs and it still tries to create the shared libs. I realize this is not the
fault of the compiler.

Here is the snipped of output from the build process:

/bin/sh ../libtool --mode=link gcc  -g -O2 -Wall  -o libgdk.la -rpath
/usr/local/lib -version-info 5:0:5 -release
1.2 -export-dynamic -L/usr/X11/lib -lXext -lX11 -lipc -lm gdk.lo gdkcc
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin
shared libraries

Thanks to everyone who posted information regarding windows versions of gtk
but I'm only interested in building this under cygwin using X.

Please check the configure script.  It could be possible that
GTK does not support static libs.  Several sofwtare do, for example
GGI
will build only as shared lib no matter what you do.  The GGI
was designed to be a shared lib only.  It could be same for GTK, I
do not know.  you could check the documents and/or configure scripts
if this is the case. You may need to modify configure script to
build dlls instead of *.so.

Does this mean that the old fork/exec problem that plagued cygwin-perl a
while back is fixed in recent snapshots? Not fixed? Partially fixed?

Gtk+ and GNOME for MingW32 are available.  They are build as shared
libs (DLLs) I do not remember URL from where I downloaded them
couple of weeks ago.

I don't think so.  I investigated this a while ago.  I looks like the problem
is due to the fork code loading the DLLs in the wrong order which causes the
DLLs in the child to be loaded in different locations than the parent.

This problem is due to a bug in cygwin-b20, and is fixed in recent
snapshots. In most cases, it is quite harmless (unless you're creating
subprocesses using fork/exec, in which case odd things may happen).

You need to ask the GTK folks about it. --disable-shared should have
created static libs only, but for some packages, that is not an option.
It's not possible to tell what the problem is from just what you've 
posted, sorry.

The modified source code as well as  GTK+ and GNOME for
MINGW32 is at: It is compiled using egcs-1.1.2, as far I remember
from
the notes on URL.

For more information about the port or GLib, GTk+ and the GIMP to
native Windows, and pre-built binary packages, see
http://www.iki.fi/tml/gimp/win32/ or

How to build static lib's

[Kevin Wright]

Hello,

I've been using cygwin for about a year and have 
always had some problems building static only 
versions of libraries such as glib and gtk+.

Here's the configure options I've tried:

./configure --disable-shared --disable-shm --disable-nls --no-recursion

However, I still end up building the .lo & subsequent .la files. 
I tried hacking the libtool files but that was useless because it gets
created during the configure process. The problem is that certain lib's
programs fail with messages such as:

gdk_imlib ERROR: Cannot load image: 
/usr/local/share/pixmaps/gnome-question.png
All fallbacks failed.

WARNING: previous dlopen of 
E:\usr\local\lib\libimlib-png.so wasn't correctly performed


Is there a way to make these libs truly static? 

I'm using gcc 2.95 and cygwin b20.1. Perhaps this is fixed in a 
newer snapshot of the cygwin1.dll but I am waiting for the 
complete installation package to be released.

TIA,

Kevin Wright

RE: How to build static lib's

[Suhaib Siddiqi]

Yes right.  that is what i was refering to.  Thought not directly
related to Gnome, but I found GTK+ and GDK+ ports very useful.

The GIMP is impressive, too. It did crashed on me with errors, once
in
a while when loading tiff.exe plug-ins.  It does crash if you
attempt to
open a tiff or jpeg file which is corrupted.

You might refer to the stuff I have available at
http://www.iki.fi/tml/gimp/win32/ . It's just GLib and GTk+ (and the
GIMP), nothing directly GNOME-related, though. Also, there is a
desperate need for documentation how to use my precompiled DLLs when
building GTk+ programs. (It is a bit complex, as you must use
gcc-2.95, and remember to use the -mno-cygwin and -fnative-struct
flags, and patch the gcc setup to use msvcrt and not crtdll. Well,
actually I don't know if it's absolutely necessary to use msvcrt in
the client program even if the gtk, gdk and glib DLLs use it.)

Here is a snippet of the output from running configure:

checking for ld used by GCC... /bin/ld.exe
checking if the linker (/bin/ld.exe) is GNU ld... yes
checking for BSD-compatible nm... /bin/nm -B
checking whether ln -s works... yes
updating cache ./config.cache
loading cache ./config.cache within ltconfig
checking for object suffix... o
checking for executable suffix... .exe
checking for gcc option to produce PIC... none
checking if gcc supports -c -o file.o... yes
checking if gcc supports -c -o file.lo... yes
checking if gcc supports -fno-rtti -fno-exceptions ... yes
checking if gcc static flag -static works... -static
checking if the linker (/bin/ld.exe) is GNU ld... yes
checking whether the linker (/bin/ld.exe) supports shared libraries... yes
checking command to parse /bin/nm -B output... ok
checking how to hardcode library paths into programs... immediate
checking for /bin/ld.exe option to reload object files... -r
checking dynamic linker characteristics... Win32 ld.exe
checking if libtool supports shared libraries... yes
checking if package supports dlls... no
checking whether to build shared libraries... no
checking whether to build static libraries... yes

It seams that the configure script is broken because even though I specify
using no static libs, it still checks for whether libtool support shared
libs and it still tries to create the shared libs. I realize this is not the
fault of the compiler.

Here is the snipped of output from the build process:

/bin/sh ../libtool --mode=link gcc  -g -O2 -Wall  -o libgdk.la -rpath
/usr/local/lib -version-info 5:0:5 -release
1.2 -export-dynamic -L/usr/X11/lib -lXext -lX11 -lipc -lm gdk.lo gdkcc
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin
shared libraries

Thanks to everyone who posted information regarding windows versions of gtk
but I'm only interested in building this under cygwin using X.
