Re: [CMake] Makefile to CMakeLists.txt (GTEST)

2010-12-07 Thread Kevyn-Alexandre Paré 
Yes it's true I didn't think of this one. It work nicely, here what I
have done:

wget http://googletest.googlecode.com/files/gtest-1.5.0.tar.bz2
tar xjvf gtest-1.5.0.tar.bz2
cd gtest-1.5.0
mkdir my-test
vim CMakeLists.txt # Add ADD_SUBDIRECTORY(my-test)
cd my-test

# SIMPLE HEADER FILE
vim source.h
void function ();

# SIMPLE SOURCE
vim source.c
#include stdio.h
void function ()
{
printf(my function to test\n);
}

# SIMPLE TEST
vim ut_source.cc
#include limits.h
#include unistd.h
#include gtest/gtest.h
#include source.h
static int something()
{
function();
return 0;
}
TEST(RRThread, CreateThread)
{
EXPECT_EQ(0, something());
}

vim CMakeLists.txt
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)

make

Thx for replying,

It seem that my simple example and using a add_subdirectory and reusing
CMakelists.txt of the gtest source solved my problem.

 I'm not sure what exactly has gone wrong here.  You might want to try
 to find the exitThread symbol to see where it lives using nm or
 strings on the libraries that you have.  If all else fails, perhaps
 check on a GTest forum?  I've never had this problem before but I
 don't recall ever using the gtest static libraries either.
  
 I pretty sure that I'm missing little detail. How can I
 implicitly add
 dependency to the object during the linking?
 
 
 I don't see anything wrong with what you have in terms of the GCC
 invocation.  You'll need to explicitly specify the libraries during
 compile time to resolve those symbols and produce a binary as far as I
 know.
 
 
 I'm not sure why you're using add_custom_target() when you could just
 use add_executable() and target_link_libraries(), but I doubt this has
 anything to do with your undefined symbol reference.

Re: [CMake] Makefile to CMakeLists.txt (GTEST)

2010-12-01 Thread Ben Medina 
Note that recent versions of gtest come with a CMakeLists.txt, so you
can just use add_subdirectory on the gtest source tree.

 Philip,

 Thx for the reply. Neither of these solutions change a thing.

 I try to play with ADD_CUSTOM_TARGET but same error...

 ADD_CUSTOM_TARGET(RRThread.o ALL COMMAND ${CMAKE_C_COMPILER} -I
 ${MICRONTRACKER_COMMON_PATH} -I${GTEST_HEADER_PATH} -lpthread -c
 ${MICRONTRACKER_COMMON_PATH}RRThread.c
 ${UNIT_TEST_PATH}common/UT_RRThread.cc)

 ADD_CUSTOM_TARGET(UT_RRThread ALL COMMAND ${CMAKE_CXX_COMPILER} -I
 ${MICRONTRACKER_COMMON_PATH} -I${GTEST_HEADER_PATH} -lpthread RRThread.o
 UT_RRThread.o ${GTEST_LIB_PATH}gtest.a ${GTEST_LIB_PATH}gtest_main.a -o
 UT_RRThread)

 Result:
 UT_RRThread.o: In function `thread_proc(void*)':
 UT_RRThread.cc:(.text+0x28): undefined reference to `exitThread()'
 ...

 I pretty sure that I'm missing little detail. How can I implicitly add
 dependency to the object during the linking?

 Regards

 Also, when you get some time, have a look at FindGTest.cmake.  It may
 help you simplify adding your tests.

Try adding the gtest.a library as well.  Also, order does matter when you
are linking static libraries so you might need to play with the ordering.

Also, when you get some time, have a look at FindGTest.cmake.  It may help
you simplify adding your tests.
