Announcing a new sub-project in gnucash: GUI in C++, Qt, CMake.

[Herbert Thoma]

Hi Christian,

cool project! I tried to build cutecash and ran into some problems:

I run SuSE 11.0 on this computer. SuSE 11.0 is not so old, however, it
lacks your required minimum versions of glib and Qt.
You require glib (and gobject, gmodule, gthread) 2.20.0 but GnuCash
only requires 2.12.0.
You require Qt 4.5.0 but I have only 4.4.0.
I changed the minimum requirements in CMakeLists.txt to glib 2.12.0
and Qt 4.4.0 and cmake completed successfully.

Compiling fails with the following error:
[ 62%] Building C object src/engine/CMakeFiles/engine.dir/engine-helpers.c.o
/home/tma/gnucash/gnucash_cvs/cutecash/src/engine/engine-helpers.c: In function ‘gnc_query2scm’:

make[2]: *** [src/engine/CMakeFiles/engine.dir/engine-helpers.c.o] Fehler 1
make[1]: *** [src/engine/CMakeFiles/engine.dir/all] Fehler 2

The problem are some section like this:
#ifndef HAVE_GUILE18
    --scm_block_gc;
#endif
in src/engine/engine-helpers.c

Do you know how to check for the guile version and how to set the HAVE_GUILE18 if required
in cmake?

Keep up this interesting work!

 Herbert.
