Mintty font problem

Mintty font problem

[Paul Ausbeck]

Cygwin setup just updated some older packages while installing a 
requested new component and now mintty does not recognize fonts 
properly. I was previously using lucinda-console but now some default 
font is being used. When I try to change the mintty font through the 
Options... dialog, the following message appears when I press Select...:

"There are no fonts installed.
  Open the Fonts folder from the Control Panel to install fonts."

I've looked through the cygwin announce history and mintty v2.3.3 
advertises some font support changes. I'm still running Windows XP on 
this machine and I'm wondering if it could be that this new version of 
mintty has not been tested on XP?

It hasn't, in fact. I'll check that.

This is fixed in the repository. Can you compile 
https://github.com/mintty/mintty/archive/master.zip and retry?

I'm having the same problem with a new XP install and cygwin, where it 
worked before.  Tried v 2.3.3, v2.3.5, and older archived v2.2.4 which 
certainly worked fine on previous XP machine.  Nothing works now, so not 
sure if it is mintty or XP setup.  Exact same XP install disk as previous.  
Different hardware.

One MS forum suggested to make sure that at least 1 printer was installed to 
make fonts visible in some applications.

Another suggested checking permissions on the font directory.

A cygwin forum suggested that there might be no monospace fonts installed 
and that mintty needs monospaced fonts only (make sense).

I've tried all the above, and no luck.

Something else suggested using tweakui to rebuild certain system folders.

I'll try that next.

Postinstall script errors on cygwin x86 install

[Tatsuro MATSUOKA]

Hello
I have tried to install Cygwin x86 in my netbook (win 10 32bit).
Only default packages were installed.
In the final panel, I saw  the following:
Postinstall script errors

Take a look at var/log/setup.log.full and see if it gives any clues as 
to why the postinstall scripts are failing.  You could also try running 
them manually.

Please check /var/log/setup.log.full for what those errors were
specifically.  What is the user you are running setup under?

Don't try so much. As I had responded before, this has been fixed in the 
repository.

Well, since that cygheap base address is changing, I guess this comes
down to BLODA.  What malware scanner are you using?  Can you exempt the
Cygwin installation from its actions?

But please try to install Cygwin into some other directory
that is not directly in the root of your drive (something like
C:\Freeware\Cygwin).

Achim.

cygcheck output as requested at http://cygwin.com/problems.html might 
help diagnose the problem:

"Run cygcheck -s -v -r > cygcheck.out and include that file *as an

I have forgetton to execute setup_x86-64 before gnuplot buliding.
Setup seems to upgrade the cygwin and gcc-5.3.0 (to 5.3.0-3).
After setup, the warning was disappeared.

multiple definition of `atan2l' on the current Cygwin

[Tatsuro MATSUOKA]

I have updated Cygwin_x86 and Cygwin_x86-64 today.
In building the gnuplot I have met the error of "multiple definition of `atan2l'".
/usr/lib/gcc/x86_64-pc-cygwin/5.3.0/libstdc++.dll.a(d005836.o):(.text+0x0): multiple definition of `atan2l'
/usr/lib/../lib/libm.a(t-d000195.o):fake:(.text+0x0): first defined here
collect2: error: ld returned 1 exit status
Makefile:777: recipe for target 'gnuplot.exe' failed
This did not occur yesterday.
Perhaps the latest change gcc-5.3.0 give this results.
At the moment a workaroud is :
LDFLAGS='-Wl,--allow-multiple-definition' \
at configure.

Tatsuro,
can you please stop to reply to different unrelated threads
instead of starting a new one ?

It mess up the archives
https://cygwin.com/ml/cygwin/2016-04/threads.html

and mail reading.

Why aren’t you using the gnuplot package in the Cygwin package repository?

> I have met the error of "multiple definition of `atan2l’".

This is doubtless because that function was just added to Cygwin in 2.5.0.

Perhaps gnuplot is providing its own copy due to a naive platform test?  Have you tried a clean reconfigure and rebuild?

My problem is solved but I do not do detailed action.
Only things are done.
 1. Windows Update
 2. Reinstall Cygwin
Perhaps 1 or 2 and both is or are related to the solving issue.
Anyway, thanks for replies.

gcc-5.3.0 for x86 has been updated to gcc-5.3.0-5

I have confirmed the mutiple definition error does not occur on gnuplot build with

Thanks!  So that's why my testcase didn't work :}

This is actually a problem in libstdc++-v3.  On platforms missing
certain long double functions libstdc++-v3 is built with stub functions
using the same name.

Jon, any chance to rebuild the gcc packages ASAP?

It is because optimizer removes the function call.

Try:

$ cat > m.cc <<EOF
#include <cstdio>
#include <cmath>

int main()
{
  long double x, y;
  scanf("%Lf %Lf", &x, &y);
  printf("%Lf\n", atan2l(x,y));

If it's that simple, why does my STC (or a simple variation thereof) not
complain?

likely because it was built before that libm had it.
Only latest cygwin 2.5.0 has it.

Those lines point to the double definition very clearly.

In Linux, libstdc++ doesn't include atan2l, only libm has it.  The
question then is: why is libstdc++ different?

Your testcase also works here.
I tried to make the test but I could not make a simple, self-contained testcase.

I can't reproduce this with a simple testcase:

  $ cat > m.cc <<EOF
  #include <math.h>

  int main ()
  {
    atan2l (1.0, 2.0);
  }
  EOF
  $ g++ -g -o m m.cc -lm -lstdc++ -lm -lstdc++

This builds and links fine for me.

Is there a chance that gnuplot accidentally provides its own atan2l on
Cygwin, despite Cygwin 2.5.0 now providing it per C99?  Or did you, by
any chance, try to rebuild gnuplot without reconfiguring the build?

Can you please provide a simple, self-contained testcase?

multiple definition of `atan2l' on the current Cygwin

[Tatsuro MATSUOKA]

Hello
I have updated Cygwin_x86 and Cygwin_x86-64 today.
In building the gnuplot I have met the error of "multiple definition of `atan2l'".
/usr/lib/gcc/x86_64-pc-cygwin/5.3.0/libstdc++.dll.a(d005836.o):(.text+0x0): multiple definition of `atan2l'
/usr/lib/../lib/libm.a(t-d000195.o):fake:(.text+0x0): first defined here
collect2: error: ld returned 1 exit status
Makefile:777: recipe for target 'gnuplot.exe' failed
This did not occur yesterday.
Perhaps the latest change gcc-5.3.0 give this results.
At the moment a workaroud is :
LDFLAGS='-Wl,--allow-multiple-definition' \
at configure.
