GCC 5.x changes the preprocessor output, which breaks gpg-error's automatic header generation (there are other threads about this online -- it's not just MinGW that's broken). What I did to get around it was to modify the cmake patch to add the -P option to GCC.

However, that is probably not portable to MSVC...
Thank you. The -P fix got me past that problem. Thank you for the bug report. As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists. If this bug is no longer persisting or relevant please change the status to resolved. |
There seems to be something wrong with the .awk files that construct the mkerrcodes.h file. But whatever the cause, the mkerrcodes.h file ends up with invalid syntax and generates errors when included in the mkerrcodes.c file and compiled. (I'm using mingw.) The mkerrcodes.h file contains structure initialization lines like: { , "GPG_ERR_E2BIG" }, where there is supposed to be a number before the first comma. Reproducible: Always Steps to Reproduce: 1. 'emerge qt' has already completed, and much of 'emerge frameworks' has completed 2. Use either 'emerge frameworks' or 'emerge --update gpg-error' 3. Actual Results: About 110 occurrences of: 'R:/build/win32libs/gpg-error/work/mingw-w64-RelWithDebInfo-1.12/mkerrcodes.h:105:5: error: expected expression before ',' token for all of the "{ , "GPG_ERR_*" }," lines. Then emerge ends. Expected Results: Completed build of gpg-error I am running Window 8.1. This system has never had any KDE installation on it before. I'm generally following the instructions from https://techbase.kde.org/Getting_Started/Build/Windows
