First, I tried compiling APR library with MinGW but got the same error about shared memory allocation support:
checking for mmap... no
checking for munmap... no
checking for shm_open... no
checking for shm_unlink... no
checking for shmget... no
checking for shmat... no
checking for shmdt... no
checking for shmctl... no
checking for create_area... no
checking for MAP_ANON in sys/mman.h... no
checking for /dev/zero... yes
./configure:Error: decision on anonymous shared memory allocation method failed
Second, I tried use binary files from APR and Apache tarballs for Win32 (compiled with MSVC).
I followed by instructions on this page http://mingw.org/mingwfaq.shtml#faq-msvcdll , but they can't help me, linking proccess continue issue "undefined reference to ..."
My decision of this problem was extract import library (.a) from libapr.dll and link it in my application. My steps:
- Create two .def files (One with __cdecl functions and second with __stdcall functions). They are: 1. libapr-c.def -------Content--------- LIBRARY libapr.dll EXPORTS apr_app_init_complete DATA apr_day_snames DATA apr_dbg_log apr_file_printf apr_month_snames DATA ... ----------------------- 2. libapr-s.def -------Content--------- LIBRARY libapr.dll EXPORTS [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] ...
-Create two import libs , using these commands:
dlltool -U --input-def libapr-s.def -l libapr-s.a
dlltool --input-def libapr-c.def -l libapr-c.a-Then, i link these libs to my app. Linking finished well without errors. But,there were errors at runtime.
After recompiling libapr-c.a (with __stdcall funcs) with new def file (i add alias for every function): ------------------ LIBRARY libapr.dll EXPORTS apr_accept = [EMAIL PROTECTED] [EMAIL PROTECTED] = [EMAIL PROTECTED] ... ------------------ there are'n runtime errors , but only for __stdcall function. :(
__cdecl functions continue call errors at runtime. And a can't to solve this problem.
