Problem with Cygwin installation: FAQ?

Problem with Cygwin installation: FAQ?

[Adam Kleczkowski]

[-- Attachment #1: Type: text/plain, Size: 1525 bytes --]

I am trying to install/compile/run GSL v. 1.0 in the Cygwin environment
(most up-to-date version), gcc 2.95.3-5. This has created a series of
various problems and I have not been successful so far.

Cygwin is installed in c:\cygwin

GSL libraries, include files etc in c:\cygwin\usr\bin etc, binaries in
c:\cygwin\bin

Testing by using example programs from the manual (pages referring to PDF
format):

Page 40:        poly.c (finding roots of the polynomial)
Page 162:       random.c (testing a random number generator)
Page 266:       vanderpol.c (Vanderpol oscilator)

Using the mingw installation.
All programs compile well, but:
a. poly.c executes with no problem
b. random.c and vanderpol.c crash giving the message:

      0 [main] A 86798653 handle_exceptions: Exception:
STATUS_ACCESS_VIOLATION
   1647 [main] A 86798653 open_stackdumpfile: Dumping stack trace to
RANDOM.EXE.stack
dump

I compile using simply
gcc -o random.exe -c random.c -lgsl -lm

I attach the programs. Any clues? In fact, I want to use random number
generators and ODE solver in my project, and these two have not compiled
well...
Thanks for a response in advance. If there is a reasonable FAQ that covers
the Cygwin installation, I would love to know where to find it. I tried to
compile GSL from the source under Cygwin (./configure, make, make install)
but run into horrific problems.

As Kees wrote, you cannot mix cygwin and mingw, if you compile *with*
cygwin1.dll then you do correct like above, if you have a dsl lib compiled
*with* mingw you need to add -mno-cygwin to your link line to get a native
windows binary.

gcc -mno-cygwin -o random.exe -c random.c -lgsl -l...

and you need to add the correct libs (I don't know them, Kees wrote about
dependencies msvcrt and so), libm, libg, libc are all the same as libcygwin.

Hi,

The Cygwin version of GSL is a third-party package made the GnuWin32
group. I don't know much about it I'm afraid -- I get the same error
as you, and I can't figure it out either.  Sorry I can't offer any
more help than that. I'm cc'ing this message to their mailing list to
see if they can offer any suggestions.

Their distribution does include the similar program "gsl-randist"
which generates random numbers correctly, so it must be possible to
get this to work -- perhaps it just requires some special Windows
compiler option that I'm not familiar with.

regards
Brian Gough

Re: [Gnuwin32-users] Re: Problem with Cygwin installation: FAQ?

[GnuWin32]

The Gnuwin32 port at http://gnuwin32.sourceforge.net/ is not a Cygwin port,
but a native MS-Windows port (it only depends on msvcrt.dll, which is
supplied on all MS-Windows systems). When running 'make check', all went
well, and there were no errors (see check.log in gsl-1.0-src.zip). The
Gnuwin32 port comes with import libraries for Mingw (GCC for MS-Windows),
MSVC and Borland C.
I'm not sure what you have been trying to do. Do you use Cygwin to compile
Gsl? Usually libraries or programs that compile well under Linux, also
compile without any change under Cygwin (configure, make, make check, make
install), and in this case I'm not sure how your problem can be solved. I
could try a compilation under Cygwin, but this will have to wait until next
weekend.
Or did you compile a program under Cygwin (i.e. with the Cygwin GCC
compiler), while linking to the Gnuwin32 dll (by means of the Gnuwin32
import library gsl.dll.a)? In that case, some things will certainly go
wrong, e.g. because Cygwin dll's use an entry point that is different from
MS-Windows dll's, and because Cygwin dll's depend on cygwin1.dll and so you
end up with a program that depends on both cygwin1.dll (because you compiled
it under Cygwin) and msvcrt.dll (because gsl.dll depends on msvcrt.dll). And
since cygwin1.dll and msvcrt.dll export the same functions, the program will
crash. If you quikview an executable, you will see on which dll's it depends
directly; so if your executable depends on cygwin1.dll, this probably is the
cause of your problem. To solve this, make sure that  Mingw-GCC comes first
in your path, before cygwin\bin, and that the GCC compiler won't look after
libraries in cygwin\lib.
If you still have problems after this, then send me some sample programs,
and I will try whether they compile and execute well on my own system
(Windows 98).

Re: [Gnuwin32-users] Re: Problem with Cygwin installation: FAQ?

[GnuWin32]

The Gnuwin32 port at http://gnuwin32.sourceforge.net/ is not a Cygwin port,
but a native MS-Windows port (it only depends on msvcrt.dll, which is
supplied on all MS-Windows systems). When running 'make check', all went
well, and there were no errors (see check.log in gsl-1.0-src.zip). The
Gnuwin32 port comes with import libraries for Mingw (GCC for MS-Windows),
MSVC and Borland C.
I'm not sure what you have been trying to do. Do you use Cygwin to compile
Gsl? Usually libraries or programs that compile well under Linux, also
compile without any change under Cygwin (configure, make, make check, make
install), and in this case I'm not sure how your problem can be solved. I
could try a compilation under Cygwin, but this will have to wait until next
weekend.
Or did you compile a program under Cygwin (i.e. with the Cygwin GCC
compiler), while linking to the Gnuwin32 dll (by means of the Gnuwin32
import library gsl.dll.a)? In that case, some things will certainly go
wrong, e.g. because Cygwin dll's use an entry point that is different from
MS-Windows dll's, and because Cygwin dll's depend on cygwin1.dll and so you
end up with a program that depends on both cygwin1.dll (because you compiled
it under Cygwin) and msvcrt.dll (because gsl.dll depends on msvcrt.dll). And
since cygwin1.dll and msvcrt.dll export the same functions, the program will
crash. If you quikview an executable, you will see on which dll's it depends
directly; so if your executable depends on cygwin1.dll, this probably is the
cause of your problem. To solve this, make sure that  Mingw-GCC comes first
in your path, before cygwin\bin, and that the GCC compiler won't look after
libraries in cygwin\lib.
If you still have problems after this, then send me some sample programs,
and I will try whether they compile and execute well on my own system
(Windows 98).

RE: [Gnuwin32-users] Re: Problem with Cygwin installation: FAQ?

[Adam Kleczkowski]

Thanks for the replies. I realise now (having also thought it through last
night) that I have neither been particularly clear in my e-mail nor
consistent in what I was trying to achieve. Thank you for all suggestions as
they helped me understand the installation procedure and the duality between
Cygwin and gnuwin32 port.
As Kees pointed out, I managed to mix the two ports. I used sources from the
gnuwin32 port in hope that I can configure and compile them into libraries
that work under Cygwin port. Since that failed, I installed gnuwin32
binaries/libraries but used Cygwin gcc to compile the test programs.
Surprisingly that worked for some of them, and left me puzzled enough to
send this query.
I have just downloaded the 'original' sources, installed them successfully
using Cygwin port and got no error messages whatsoever. Thanks again for
help,
Thanks also to all who are working on gnuwin32, Cygwin and gsl.

Problem with Cygwin installation: FAQ?

[Adam Kleczkowski]

[-- Attachment #1: Type: text/plain, Size: 1525 bytes --]

I am trying to install/compile/run GSL v. 1.0 in the Cygwin environment
(most up-to-date version), gcc 2.95.3-5. This has created a series of
various problems and I have not been successful so far.

Cygwin is installed in c:\cygwin

GSL libraries, include files etc in c:\cygwin\usr\bin etc, binaries in
c:\cygwin\bin

Testing by using example programs from the manual (pages referring to PDF
format):

Page 40:        poly.c (finding roots of the polynomial)
Page 162:       random.c (testing a random number generator)
Page 266:       vanderpol.c (Vanderpol oscilator)

Using the mingw installation.
All programs compile well, but:
a. poly.c executes with no problem
b. random.c and vanderpol.c crash giving the message:

      0 [main] A 86798653 handle_exceptions: Exception:
STATUS_ACCESS_VIOLATION
   1647 [main] A 86798653 open_stackdumpfile: Dumping stack trace to
RANDOM.EXE.stack
dump

I compile using simply
gcc -o random.exe -c random.c -lgsl -lm

I attach the programs. Any clues? In fact, I want to use random number
generators and ODE solver in my project, and these two have not compiled
well...
Thanks for a response in advance. If there is a reasonable FAQ that covers
the Cygwin installation, I would love to know where to find it. I tried to
compile GSL from the source under Cygwin (./configure, make, make install)
but run into horrific problems.
