Thanks. Easy to forget that there are 3 ways to link to external libraries. -------- Original message --------From: Sven Barth via fpc-pascal <fpc-pascal@lists.freepascal.org> Date: 17/02/2024 00:29 (GMT+00:00) To: FPC-Pascal users discussions <fpc-pascal@lists.freepascal.org> Cc: Sven Barth <pascaldra...@googlemail.com> Subject: Re: [fpc-pascal] Can FPC link a program with static (.a) libraries on Windows Tony Whyman via fpc-pascal <fpc-pascal@lists.freepascal.org> schrieb am Sa., 17. Feb. 2024, 00:50:I have a Pascal program, compiled with FPC 3.2.2 and which appears to happily link and run with a static library compiled with gcc and having a ".a" prefix on linux. The functions in the static library and declared as external functions using the "external <libname> name <function name>" directive. The "".a" library is copied to the same directory as the program unit before compiling and linking.
However, compiling the same program on Windows always seems to result in the loader complaining that the corresponding <libname>.dll is not present, indicating that instead of linking with the static library, the program is attempting to "statically" load the correspoinding dll at initialisation time. I have tried to force it to link with the static library (e.g. using the -Xt command line switch) but no luck. Hence the question, does FPC 3.2.2 support linking with static libraries on windows?"external <libname> name <funcname>" is for dynamic linking. For static linking you need to leave out the <libname> and instead use "{$linklib <libname>}" or even "{$linklib <libname>, static}" . That will also work on Linux. Regards, Sven
