Җ: Download and copy WinGNU’s make.exe and dependencies into path where perl is installed (in my case C:\Program Files (x64)\perl\c\bin)
– add C:\Program Files (x64)\perl\c\bin to system PATH, so Perl/CPAN can find gcc.exe and make.exe
– add to C:\Program Files (x64)\perl\perl\lib\CPAN Config.pm:
- cpan > install Hash::StoredIterator12'make' => q[C:\\Program Files (x64)\\perl\\c\\bin\\make.exe],'make_arg' => q[CC=C:\\Program Files (x64)\\perl\\c\\bin\\gcc.exe],
– cd C:\Program Files (x64)\perl\cpan\build\Devel-Camelcadedb-v2023.1-6 (where CPAN failed last time to make install)
– make
– make install - Q: How to converting strings to Resource IDs?
A: To convert a string to a named resource ID (within a string table defined in resource.h), you’ll typically need to implement an X-macros for converting resource IDs to strings. Please note, that builtin MSVS resource editor doesn’t support editing them (but it works) - Q: WSL’да Qt creator’ның менюларын ничек зурайтырга?
