Hi all,
I have some C code that embeds perl into a C application.
If I compile my code with:
cl.exe <result of "perl -MExtUtils::Embed -e ccopts">
and then:
link <result of "perl -MExtUtils::Embed -e ldopts">
the resulting dll works. But if I compile it with cmake, my code
always crashes, because a perl structure (a global pointer) is left
uninitialised, and is always NULL. It seems that cmake inserts
something that changes the building process.
How can I find what commands are executed when the code is
compiled/linked?
I even tried the following:
EXECUTE_PROCESS ( COMMAND ${PERL_EXECUTABLE}
-MExtUtils::Embed -e ccopts
OUTPUT_VARIABLE PERL_OUTPUT
RESULT_VARIABLE PERL_RETURN_VALUE )
IF ( NOT PERL_RETURN_VALUE )
STRING ( REPLACE "-O1" "" ADDITIONAL_PERL_CCOPTS ${PERL_OUTPUT} )
ENDIF ( NOT PERL_RETURN_VALUE )
EXECUTE_PROCESS ( COMMAND ${PERL_EXECUTABLE}
-MExtUtils::Embed -e ldopts
OUTPUT_VARIABLE PERL_OUTPUT
RESULT_VARIABLE PERL_RETURN_VALUE )
IF ( NOT PERL_RETURN_VALUE )
SET ( ADDITIONAL_PERL_LDOPTS ${PERL_OUTPUT} )
ENDIF ( NOT PERL_RETURN_VALUE )
SET ( CMAKE_C_FLAGS "-DUSE_TCL_STUBS ${ADDITIONAL_PERL_CCOPTS}" )
SET ( CMAKE_C_FLAGS_RELEASE "" )
SET ( CMAKE_C_FLAGS_DEBUG "" )
SET ( CMAKE_SHARED_LINKER_FLAGS ${ADDITIONAL_PERL_LDOPTS} )
SET ( CMAKE_SHARED_LINKER_FLAGS_RELEASE "" )
SET ( CMAKE_SHARED_LINKER_FLAGS_DEBUG "" )
But it didn't change anything. The produced dll still crashes. Any
ideas?
Regards,
George
Actually, looking at the two dlls (one produced with a nmake makefile
I have written, and the one built with cmake), they import different
functions:
nmake cmake
300 Perl_get_context 300 Perl_get_context
265 Perl_Tstack_sp_ptr 265 Perl_Tstack_sp_ptr
214 Perl_Tmarkstack_ptr_ptr 214 Perl_Tmarkstack_ptr_ptr

51C boot_DynaLoader 51C boot_DynaLoader
3E1 Perl_newXS 3E1 Perl_newXS
3E2 Perl_newXS_flags
197 Perl_Isv_yes_ptr
How is possible to use the same definitions & link flags and get
different results?

And here are the exact commands: the top line is my nmake commands, and
the second line is the cmake command:
"C:\Program Files (x86)\Perl/bin/perl.exe" "C:\Program Files
(x86)\Perl\lib\ExtUtils/xsubpp" -typemap "C:\Program Files
(x86)\Perl\lib\ExtUtils\typemap" .\Tcl.xs > .\Tcl.c
cd C:\Users\petasis\Ellogon\lib\tclperl-3.2

(x86)/Perl/lib/ExtUtils/xsubpp" -typemap "C:/Program Files

cl -nologo -c -W3 -EHsc -FD -FpBuildTemp -Gs -D "WIN32" -D "NDEBUG" -D

-DPERL_MSVCRT_READFIX -I"C:\Program Files (x86)\Perl\lib\CORE"
-I"C:\Program Files (x86)\Tcl\include" -I"." .\tclperl.c .\tclthread.c
.\Tcl.c
C:\PROGRA~2\MICROS~1.0\VC\bin\cl.exe
@C:\Users\George\AppData\Local\Temp\nm41D2.tmp
tclperl.c
Any idea on how can I get the contents of
"C:\Users\George\AppData\Local\Temp\nm41D2.tmp"? It is created and
deleted so fast, that it is impossible to see it...
George
