Dear all,
I did the following small test program and I'm experiencing a strange behavior:
- - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - -
//main.cpp
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Input.H>
#include <FL/Fl_Output.H>
int main() {
Fl_Window win(400, 600, "TestWindow");
win.begin();
Fl_Output test(50, 50, 300, 500, "Test");
win.end();
win.show();
return Fl::run();
}
- - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - -
If I issue an fltk-config --compile main.cpp everything works and I get the
working executable file.
If I create this cmake file:
- - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - -
#CMakeList.txt
cmake_minimum_required(VERSION 2.8)
project(test)
find_package(FLTK REQUIRED NO_MODULE)
find_package(OpenGL REQUIRED)
set(test_SRCS
main.cpp
)
set(test_HDRS
)
add_executable(test ${APPLICATION_EXECUTABLE_SYSTEM} ${test_SRCS} ${test_HDRS})
target_link_libraries(test ${FLTK_LIBRARIES})
target_link_libraries(test ${OPENGL_LIBRARIES})
- - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - -
I can cmake it using the GUI and create the makefile without any problem, but
when I issue the make command, this is the output error from the linker (and
not from the compiler):
- - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - -
Linking CXX executable test
CMakeFiles/test.dir/main.cpp.o: In function `main':
main.cpp:(.text+0x5f): undefined reference to `Fl_Output::Fl_Output(int, int,
int, int, char const*)'

make[2]: *** [test] Error 1

- - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - - 8< - - - -
Do you know how to solve it? I think I'm missing some dependencies, but I don't
know which ones.
Thank you, regards
MDC
