Hello, I tried to install sample_fe in gcc-dev. I get errors dealing with #include "gtype-sample_fe.h" and #include "gt-sample_fe-sfe1.h" In the sample_fe (that woked well in gcc4.5) there is only #include "gtype-sample_fe.h" not "gt-sample_fe-sfe1.h" when I call make I get this error: libbackend.a(i386.o):(.rodata+0x242c): undefined reference to `gt_ggc_mx_lang_tree_node' libbackend.a(i386.o):(.rodata+0x2430): undefined reference to `gt_pch_nx_lang_tree_node' /usr/bin/ld: Dwarf Error: Offset (17707) greater than or equal to .debug_str size (1397). libbackend.a(cgraphunit.o):(.rodata+0xc): undefined reference to `gt_ggc_mx_lang_tree_node' libbackend.a(cgraphunit.o):(.rodata+0x10): undefined reference to `gt_pch_nx_lang_tree_node' /usr/bin/ld: Dwarf Error: Offset (15649) greater than or equal to .debug_str size (1103). libbackend.a(ggc-page.o): In function `gt_ggc_m_S': /export/home/charfi/Bureau/build_uml/gcc/../../gcc-dev/gcc/ggc-page.c:1304: undefined reference to `gt_ggc_mx_lang_tree_node' collect2: ld returned 1 exit status if I add #include "gt-sample_fe-sfe1.h" and call make I get this different error: ../../gcc-dev/gcc/sample_fe/sfe1.c:173:31: error: gt-sample_fe-sfe1.h: No such file or directory I do not change the make_lang.in. any idea ? Thank you very much Asma
