All, Is this a bug or is it me. Looks like a bug in libgsf 1.14.28-1 in the header file: /usr/include/libgsf-1/gsf/gsf-libxml.h If you attempt to include this header file you receive the error: /usr/include/libgsf-1/gsf/gsf-libxml.h:26:25: fatal error: libxml/tree.h: No such file or directory #include <libxml/tree.h> ^ compilation terminated. Example: #include <stdio.h> #include <libxml/tree.h> void main (int argc, char *argv[]) { printf("testing include\n"); } 17:01 phoinix:/dat_e/tde/tstbld/tmp> gcc -o tst tst.c tst.c:3:25: fatal error: libxml/tree.h: No such file or directory #include <libxml/tree.h> ^ compilation terminated. If someone will confirm this is a bug and not me being dense -- I'll file it. -- David C. Rankin, J.D.,P.E.
