Re: [Help-gsl] Building gsl-1.15 under MinGW

[Armin Armbruster]

Hi Rob,

Thanks for your reply.

here's gcc -v:

$ gcc -v
Using built-in specs.
COLLECT_GCC=C:\MinGW\bin\gcc.exe
COLLECT_LTO_WRAPPER=c:/mingw/bin/../libexec/gcc/mingw32/4.5.2/lto-wrapper.exe
Target: mingw32
Configured with: ../gcc-4.5.2/configure 
--enable-languages=c,c++,ada,fortran,objc,obj-c++ --disable-sjlj-exceptions --wi
th-dwarf2 --enable-shared --enable-libgomp --disable-win32-registry 
--enable-libstdcxx-debug --enable-version-specific-r
untime-libs --disable-werror --build=mingw32 --prefix=/mingw
Thread model: win32
gcc version 4.5.2 (GCC)


Some more background:
- I'm using the latest MinGW (downloaded from 
http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/mingw-get-inst/),
 mingw-get-inst-20110802.exe).
- $ help ==>GNU bash, version 3.1.17(1)-release (i686-pc-msys)
- my host OS is MS Windows XP, SP3
- gsl downloaded from ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz

Last night I've tried to build the same gsl on my computer at home (running 
Windows 7 Home Premium, SP1, 64 bit OS). I used the same MinGW installer and 
the same GSL package and make ran without problems.

I compared the config.log files in both cases (see attachment 
config_log_diff.txt). The only significant difference that I can see is that 
uname -s returns MINGW32_NT-5.1 on the XP machine and MINGW32_NT-6.1 on the 
Win7 machine.

The one thing I noticed is, that the resulting config.h is a direct copy of 
config.h.in!!! The only difference is the first line added to config.h. That 
makes me believe that something with awk and/or sed isn't working properly. I 
don't have a full understanding of the configure script but from what I 
understand it is taking the config.h.in file as a template and mangles it based 
on some test results to turn on some of the defines. Is that right?
According to the config.log file some of the HAVE_xxx switches should be turned 
on, for example at the very bottom of the config.log file in the confdefs.h 
section I see
#define HAVE_DECL_ISINF 1
but in config.h the corresponding line is the original
#undef HAVE_DECL_ISINF

I attached the config.log and config.h file.
Does anybody have an idea what is going on?
By the way, I tried an older version of MinGW (installer 
mingw-get-inst-20100831.exe) with the same result.

Meanwhile I've followed John C.'s advice and installed the binary for gsl-1.13. 
Still, I wouldn't mind finding out what's going on, so thanks in advance for 
any help.

Thanks,
Armin
