Thanks. Easy to forget that there are 3 ways to link to external libraries.

Subject: Re: [fpc-pascal] Can FPC link a program
with static (.a) libraries on Windows Tony Whyman via fpc-pascal
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 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 .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 name " is for dynamic linking. For
static linking you need to leave out the and instead use "{$linklib
}" or even "{$linklib , static}" . That will also work on
Linux. Regards, Sven
