convert .dll.a to dll

Question

I download a autotrace library to use in my java project but it contains only (libautotrace.a, libautotrace.la, libautotrace.dll.a and header)

my question: is it possible to convert libautotrace.dll.a to dll library?

Answer 1

You can not.

The dot-a files you have were compiled for a Unix system, and can not be directly converted to a Windows format.

You will need to find a windows-native build or the source code to build it yourself.

Answer 2

I found this command for generat a dll:

gcc -shared -o libproj.dll -Wl,--out-implib=libproj.dll.a -Wl,--export-all-symbols -Wl,\ --enable-auto-import -Wl,--whole-archive libproj.a -Wl,--no-whole-archive /c/mingw/lib/libmingw32.a

but I have this error : "undefined reference to " ( in many classes)

I try also :

ar -x libautotrace.a to have .o and generat a dll with

gcc -Xlinker --add-stdcall-alias -shared -o but I have the same error
