Re: Compiling gtk error - png ???

[Jose Marcio Martins da Cruz <Jose-Marcio Martins ensmp fr>]

Maybe someone may help us... glib developpers, maybe...

There was an error before this one. When makefile tried to create gdk-pix-buf/gdk-pixbuf.loaders file there was the following error, which I reproduce, running it by hand :

./gdk-pixbuf-query-loaders libpixbufloader-static-png.la
# GdkPixbuf Image Loader Modules file
# Automatically generated file, do not edit
#
Cannot load loader /export/private/sources/gtk/2.2.1/gtk+-2.2.1/gdk-pixbuf/libpixbufloader-static-png.la

This happens not only with png, but with all image formats.

The error happens at a g_module_open call : line 76 of queryloaders.c file.

So I added some debuging lines :

        module = g_module_open (path, 0);
+        fprintf(stderr, "PATH = %s\n", path);
+        if (module == NULL)
+                fprintf(stderr, " module == NULL\n");
        if (module &&

I got the following :

./gdk-pixbuf-query-loaders libpixbufloader-static-png.la
# GdkPixbuf Image Loader Modules file
# Automatically generated file, do not edit
#
PATH = /export/private/sources/gtk/2.2.1/gtk+-2.2.1/gdk-pixbuf/libpixbufloader-static-png.la
 module == NULL
Cannot load loader /export/private/sources/gtk/2.2.1/gtk+-2.2.1/gdk-pixbuf/libpixbufloader-static-png.la

The file *.la is there. Library file *.a is inside .libs directory.

If I launch this with a truss, I got the following :

...

fstat64(2, 0xFFBFE188)                          = 0
PATH = write(2, " P A T H   =  ", 7)                    = 7

write(2, "\n", 1)                               = 1
 module == NULL
write(2, "   m o d u l e   = =   N".., 16)      = 16

It seems to come from glib module, but I don't know glib library.

Maybe the problem may come from libtool/configure/Makefile...

Maybe someone has an idea.
