Hello,
I need a custom command in my build process.
The tool that I am using has a small problem, I have to insert a line of code in
the output file manually:
#include <gtk/gtk.h>
I tried this with echo and output redirection:
echo "#include <gtk/gtk.h>" > images.c
The tool, gdk-pixbuf-csource, is not able to generate a file, therefor its output has to be
redirected to the file too:
gdk-pixbuf-csource --raw pix1 ./images/pix1.png >> images.c
I can get it work one linux and win32 system, but with different syntax:
This works on a win32 System:
ADD_CUSTOM_COMMAND (OUTPUT ${CMAKE_CURRENT_SOURCE_DIR}/images.c
COMMAND ${CMAKE_COMMAND} -E echo "\#include <gtk/gtk.h>" >
images.c
COMMAND gdk-pixbuf-csource --raw pix1 ./images/pix1.png >>
images.c
DEPENDS ./images/pix1.png )
This works on a linux System:
ADD_CUSTOM_COMMAND (OUTPUT ${CMAKE_CURRENT_SOURCE_DIR}/images.c
COMMAND echo "\"""#include""<gtk/gtk.h>" "\"" > images.c
COMMAND gdk-pixbuf-csource --raw pix1 ./images/pix1.png >>
images.c
DEPENDS ./images/pix1.png )
I tried many variations of above examples, but I can't get running on both systems with the same
syntax, any idea what might be right?
Perhaps there is another way then "echo" to write something in a file, I tried FILE(WRITE) but I
failed with this.
I could make a file with the include line already inserted and than try to copy it, I saw some
commands for that, is this the better Way? Actually I don't prefer this, I don't want to have a
strange single-line source file in the project.
regards
Arne
