happily link and run with a static library compiled with gcc and having <br>
a ".a" prefix on linux. The functions in the static library and declared <br>
as external functions using the "external <libname> name <function <br>
name>" directive. The "".a" library is copied to the same directory as <br>
the program unit before compiling and linking.<br>
<br>
However, compiling the same program on Windows always seems to result in <br>
the loader complaining that the corresponding <libname>.dll is not <br>
present, indicating that instead of linking with the static library, the <br>
program is attempting to "statically" load the correspoinding dll at <br>
initialisation time.<br>
<br>
I have tried to force it to link with the static library (e.g. using the <br>
-Xt command line switch) but no luck.<br>
<br>
Hence the question, does FPC 3.2.2 support linking with static libraries <br>
on windows?<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">"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. </div><div dir="auto"><br></div><div dir="auto">Regards, </div><div dir="auto">Sven </div><div dir="auto"><div class="gmail_quote"><blockquote style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" class="gmail_quote">
