Ok, with Dror's and William's help I'm up and running with APR. Now, what
about static linking with APRICONV?
Starting with Dror's HelloWorld DSW (which compiles, links, and runs fine
with just APR), I added the lines:
# #include "apr_iconv.h"
# ...
# apr_iconv_open( 0, 0, 0, 0 );
I also added the "apriconv-1/include" directory to the search path, and
static library ("/libd/apriconv-1.lib"). Compiled fine, but linker produced
this error:
# Main.obj : error LNK2019: unresolved external symbol "int __stdcall
apr_iconv_open(char const *,char const *,struct apr_pool_t *,void * *)"
(?apr_iconv_open@@YGHPBD0PAUapr_pool_t@@[EMAIL PROTECTED]) referenced in
function
_main
# .\Debug/AprHelloWorld.exe : fatal error LNK1120: 1 unresolved externals
I tried declaring API_DECLARE_STATIC, but that doesn't seem to change
things. Any suggestions?
