Sorry if this is a dup, I hit send on the previous message too soon... Hello, First, I'm fairly new to gcc so if this isn't the right list plese direct me to the correct one.
I have some code which compiles a shared object, it compiles fine on Red Hat 8 and even on Solaris for Intel. I'm now attempting to compile this same code of Windows XP using Cygwin. This shared object calls functions in the java VM (jvm.dll on windows). When I compile on Windows I get an error stating that it can't find the function JNI_GetCreatedVms function. I'm sure that has to do with the way the jvm.dll is compiled n windows and the calling convention, but I can;t figure it out. I've looked for the past two days and havn't found that much. can anyone lend me a helping hand? I have search teh web and found several sources of info (inonit.com etc..) but none have solved my problem. I'm using g++ 3.2 20020927 (prerelease) which came with cygwin (I downloaded cygwin last week). Here is the command I am passing to g++ ad the output: g++ -Wl,--add-stdcall-alias -mno-cygwin -I. -I../common -Ic:/cygwin/usr/java/include -Ic:/cygwin/usr/java/include/win32 -shared -o Tool.dll Tool.cpp -Lc:/cygwin/usr/java/lib -ljvm /cygdrive/c/temp/ccDembDG.o(.text+0x1dac):Tool.cpp: undefined reference to `_ imp__JNI_GetCreatedJavaVMs@12' /cygdrive/c/temp/ccDembDG.o(.text+0x1e23):Tool.cpp: undefined reference to `_ imp__JNI_GetCreatedJavaVMs@12' make: *** [NPITool.dll] Error 1 I needthe DLL to compile with no dependency on cygwin, hence the -mno-cygwin. The -Wl,--add-stdcall-alias is something I just added after reading information at http://www.inonit.com/cygwin/jni/invocationApi/execute.html before it was just -Wall.
