[Gnash-dev] Linking problems on cross-compile

[mendez]

Dear all,

Well, I am stuck. I can't seem to get around a linking error while  
trying to cross compile the latest gnash: linux to windows.

The error is as follows:

It seems that the "__imp__" prefix is the problem, though I am not  
sure of that. I am also not sure exactly how to solve this but I have  
tried a number of solutions.

I tried setting "--enable-shared=no" during configure. That didn't work.

I tried setting "LDFLAGS=--enable-auto-import" that didnt work either.  
Actually the configure didnt even work (apparently some line was  
scrambling my LDFLAGS and giving it to CC who promptly complained.

I have retorted to force it down the Makefiles throat. That didnt work either.

According to the undefined references it is searching for  
"lt_dlsetsearchpath" with the "__imp__" prefix. A quick search on that  
told me that the function does exist inside libltdl/ltdl.c but for  
some reason it cant be linked against.

Anybody wants to venture a guess? I would really appreciate it.
