Hi!I'll try to make the xdimsum package for cygwin but fails in the link step. The cause is undefined references to 1) _pow_ii and other symbols that seems to be defined in libf2c.a
2) _fegetexceptflag and other symbols that seems to be defined in libmingwex.aActually, I got more or less the same result when trying to compile a small test task with xc so I seem to have a general problem linking iraf tasks. If anyone has any idea of what's wrong or knows where you can get a xdimsum binary for cygwin it would be greatly appreciated./Mattias Ergon (Stockholm University)Full log follows:Subdirectory src/xdsrc is up to date

Firstly, I've put an XDIMSUM binary for Cygwin on the downloads page for you and didn't see any problems with the compilation.I've never seen the message about 'auto-importing has been activated ....." but this may be the cause of the problem if it is keeping the f2c library from linking correctly. IRAF uses its own version of the F2C binary and libf2c.a that should be picked up automatically so long as you have the $iraf and $IRAFARCH environment variables set to allow compilation. You might try reinstalling the GCC compiler from a different site in case something went wrong originally. Something else to try is to cd to the xdimsum$src directory and try linking with [code:1:880de5ab3c]xc -dv -Nz -p xdimsum x_xdimsum.o libpkg.a -lxtools -o xx_xdimsum.e[/code:1:880de5ab3c]And make sure the path to all the iraf libraries look correct, and that indeed you have a libf2c.a in the $iraf/unix/bin.cygwin directory.-Mike

Hi!Thanks a lot for the xdimsum binary! I've installed it and it works just fine!About the linking problem i've tried to compile my simple test script with the d and v flags set. As far as I can see the libf2c.a is not linked. The paths to the iraf libraries seems to be correct however. Full log follows here:[code:1:a995f5a22b]cd /home/Mattias-Ergon/test

Could you please go to the $iraf/unix/bin.cygwin directory and post the output of an "ls -l" command? Not only is the libf2c.a missing from the link line, but the libcompat.a library from that directory as well.Also, is this an IRAF you got from this site or someplace else (I know that somewhere on the net somebody's posted installation instructions for a version we had nothing to do with).-Mike

Try creating the following symbolic link and redefining your environment:[code:1:6dcccc6188]
ln -s /home/Mattias-Ergon/iraf/ /iraf
setenv iraf /iraf/iraf/ <---- trailing '/' required
setenv IRAFARCH cygwin
source $iraf/unix/hlib/irafuser.csh
[/code:1:6dcccc6188]I have a feeling the '-' in the pathname is messing up the bits of filename translation that go on when mapping the f2c/compat libraries into paths. As far as I can tell, this is the only difference between your broken system and my working one.-Mike

Hi again!Unfortunately changing $iraf doesn't help. So it looks like we're stuck. Maybe I should try to reinstall both cygwin and iraf in case something went wrong during installations. Thanks for you help anyway!
