<P><FONT SIZE=2>I opened a bug report for this because it seems odd that FIND_PATH and FIND_LIBRARY both have their mode set to "ONLY" and one works and the other doesn't.<BR>

<BR>
So "gcc-fm.exe main.c -rdynamic" fails ? <BR>
Yes, it fails.<BR>
<BR>
Does "gcc-fm.exe main.c -shared" work ? <BR>
Yes, -shared seems to work.<BR>
<BR>
I'm still having success with FIND_PATH, but FIND_LIBRARY fails:<BR>
<BR>
In toolchain.cmake:<BR>
INCLUDE( CMakeForceCompiler )<BR>
SET( CMAKE_SYSTEM_NAME Linux )<BR>
CMAKE_FORCE_C_COMPILER( gcc-fm GNU )<BR>
CMAKE_FORCE_CXX_COMPILER( g++-fm GNU )<BR>
SET( CMAKE_FIND_ROOT_PATH<BR>
"C:/gcc-fm"<BR>
"C:/Program Files/Eracom/ProtectProcessing Orange SDK"<BR>
"C:/Program Files/Eracom/ProtectToolkit C SDK" )<BR>
SET( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER )<BR>
SET( CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY )<BR>
SET( CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY )<BR>
<BR>
In CMakeLists.txt<BR>
FIND_PATH( ERACOM_PPO_INCLUDE_DIR fmerr.h )<BR>
FIND_PATH(ERACOM_PTKC_INCLUDE_DIR cryptoki.h )<BR>
FIND_LIBRARY( ERACOM_XXX_LIBFMCRT_LIBRARY libfmcrt<BR>
PATH_SUFFIXES armfm )<BR>
FIND_LIBRARY( ERACOM_XXX_CRYPTOKI2_LIBRARY cryptoki2 )<BR>
<BR>
Both the FIND_PATH's pass and both FIND_LIBRARY's fail again. I thought maybe it's because the paths have a space so I moved them to a folder that has no spaces and still the same issue.<BR>
<BR>
Here are all the paths:<BR>
C:\Program Files\Eracom\ProtectToolkit C SDK\include\cryptoki.h<BR>
C:\Program Files\Eracom\ProtectProcessing Orange SDK\include\fmerr.h<BR>
C:\Program Files\Eracom\ProtectToolkit C SDK\lib\cryptoki2.lib<BR>
C:\Program Files\Eracom\ProtectProcessing Orange SDK\lib\armfm\libfmcrt.a<BR>
<BR>

Ok.<BR>
SET( CMAKE_FIND_ROOT_PATH<BR>
"C:/Program Files/Eracom/ProtectProcessing Orange SDK"<BR>
"C:/Program Files/Eracom/ProtectToolkit C SDK")<BR>
<BR>
and then in the CMakeLists.txt:<BR>
<BR>
FIND_LIBRARY( ERACOM_XXX_LIBFMCRT_LIBRARY fmcrt<BR>
PATH_SUFFIXES armfm )<BR>
<BR>
FIND_PATH( ERACOM_PTKC_INCLUDE_DIR cryptoki.h )<BR>
<BR>
should work.<BR>
If the library is not found, there is probably still an issue with using the<BR>
correct prefixes/suffixes due to using Windows as a host (I don't think too<BR>
many people have done this yet with cmake).<BR>
<BR>

<BR>
Just using "fmcrt" in find_library() should be enough, cmake will add the<BR>
necessary prefixes/suffixes itself.<BR>
