Hello Andi, thank you for your answer. I modified the sfe1.c as you suggested. previous error disappears but I get 2 other errors generated while calling make bootstrap DEBUG_ANDI: gsfe - .. ../libcpp/libcpp.a ../libiberty/libiberty.a .. .. -O2 -g -fomit-frame-pointer -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Wmissing-format-attribute -DHAVE_CONFIG_H .. stage1/xgcc -Bstage1/ -B/usr/local/i686-pc-linux-gnu/bin/ -O2 -g -fomit-frame-pointer -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Wmissing-format-attribute -DHAVE_CONFIG_H -o gsfe sample_fe/gsfe.o \ version.o prefix.o intl.o ../libcpp/libcpp.a ../libiberty/libiberty.a /usr/lib/crt1.o: In function `_start': ../sysdeps/i386/elf/start.S:115: undefined reference to `main' collect2: ld returned 1 exit status make[2]: *** [gsfe] Erreur 1 make[2]: Leaving directory `/home/charfi/Desktop/gccobj/gcc' make[1]: *** [stage2_build] Erreur 2 make[1]: Leaving directory `/home/charfi/Desktop/gccobj/gcc' make: *** [bootstrap] Erreur 2 I am calling ./configure after creating an other directory (not related in the source directory) named gcc-obj. this time, I think the error comes from the driver (gsfe); xhnich line should I modify ;) thank you very much Asma ----- Message d'origine ---- De : Andi Hellmund <mail@xxxxxxxxxxxxxxxx> À : charfi asma <charfiasma@xxxxxxxx> Cc : gcc-help@xxxxxxxxxxx Envoyé le : Ven 4 juin 2010, 17h 04min 38s Objet : Re: [GCC front end] trying to install sample_fe but fail in make Hey, > I try to install "sample_fe" following the steps described in Andi Blog : > http://blog.lxgcc.net/?p=181 Thanks for trying this :-) And thanks for catching this silly mistake! > I put the sample_fe in the gcc directory (whith the other fe directory : > java, cp, ...) > I configure with ./configure --enable-languages=sample_fe > when I call make, I get this errors: Generally, you should follow the install instructions on http://gcc.gnu.org/install/ and NOT call configure from the source directory, but from a separated build directory. > make > ...build/gengtype.o build/gengtype-lex.o build/gengtype-yacc.o \ > build/errors.o ../build-i686-pc-linux-gnu/libiberty/libiberty.a > build/gengtype > /home/charfi/Desktop/gcc-4.1.0/gcc/sample_fe/sfe1.c:24: stray GTY marker > make[2]: *** [s-gtype] Erreur 1 > make[2]: Leaving directory `/home/charfi/Desktop/gcc-obj/gcc' > make[1]: *** [all-gcc] Erreur 2 > make[1]: Leaving directory `/home/charfi/Desktop/gcc-obj' > make: *** [all] Erreur 2 > > I think it is reltaed with GTY and gengtype but I do not realy understand > how to correct it. Yes, I think that as well. You could possibly fix this by changing line 24 of sfe1.c from struct GTY(()) lang_identifier to struct lang_identifier GTY(()) But, I'm not totally sure if this version of sample_fe will work anyway with your version, because I just tested it with 4.4.x and you seem to compile a 4.1.0 version. If you for some reason require to use 4.1.0, then please continue trying and let me know if you face further problems. Otherwise, I would recommend using a 4.4.x. I'll upload a 4.5.0-based version this weekend, so that you could also use gcc-4.5.0 for your experiments. I'll update the web page with a modified version ... Best regards, Andi
