I help maintain parts of PLplot (notably the Fortran and Tcl bindings and the Windows platform). PLplot builds fine with gfortran (on Linux, Cygwin, MinGW) - no problem. Regards, Arjen
Re: Compiling GCC under Cygwin
Hi Angelo, true, it is not Fortran-specific. I used this mailing-list because I am familiar with it and because the purpose of this attempt was to see if I can in some way contribute other things than bug reports ;). The error you refer to is actually an error in the C source, whereas the build error I got has something to do with the Makefiles. As for the build experiment itself: - I downloaded the 4.8.1 source - I configured the Makefiles with this command: ./configure --prefix=d:/gcc-src/gcc - Then I ran make and the error message I reported before. (It is not impossible that the error is a consequence of the permission errors I got before - they are not completely gone yet, as they re-surfaced in another project.) If I understand the issue correctly, I can probably get rid of it tomorrow - as then the laptop will be connected to the proper domain. Anyway. thanks for the reaction. I will see if I can analyse it further.

Re: Compiling GCC under Cygwin
Hi Angelo, well, the DOS-style path only caused a warning in the configure step, so I assumed it was okay. It was not apparently. Building out-of-source is an instruction I must have missed. So, I tried again. The problem I reported before has gone, but I still get a file permission problem later on. I have not been able to solve it, even though my laptop is now connected to the domain, I have instructed the build process to use my home directory and I have set umask to - all suggestions I found or was told they might solve the problem. If anyone knows what to do about it, I would very much like to hear about it. My Google foo is failing me in unearthing a definite solution, I am afraid.

Re: Compiling GCC under Cygwin
Hi Angelo, I found a reference to this sort of problems in the Cygwin FAQs, but this turned out to be a dead-end too. So I thought, I'd try MinGW/MSYS instead. It started off fairly well, however: - For some reason the gcc compiler did not like the /d/gcc-src/... path (from $srcdir) - it could not find the include file gmp-h.in. So I changed that to d:/gcc-src/... And that worked, until ... - the source file gen-fac.c was missing from the build directory for gmp. So I copied the various source files manually. And that worked, until ... - the assert.lo file was missing, which is necessary for libgmp. That file is nowhere in the build directory. So now I am definitely stuck. I can try to contact the Gygwin people and hope for the best. Or any of you might know the solution wrt MinGW.

Re: Compiling GCC under Cygwin
Hi Angelo, well, after a somewhat bumpy start on the Cygwin list, I did get the information I needed. It turned out that the directories and files I had created under Windows had the permission 000 according to Cygwin, but I could still read the files and enter the directories, because the Windows permissions allowed it. However, if the build process _copied_ a file to the work directory, it inherited the 000 permission and this time it was properly translated to the equivalent Windows permissions. (At least, that is my interpretation of what was going on) I repaired the parent directory's permissions and now the build is continuing.
