Hi, guys, I am trying to build gcc-3.3.6 from Index of /mirrors/gcc/releases/gcc-3.3.6 (bigsearcher.com)<https://bigsearcher.com/mirrors/gcc/releases/gcc-3.3.6/> , the following error message occurred. Could you please tell me how to fix it? My host computer: Dell Inspiron 16 plus 7630. GCC on host: gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 under WSL. Why do I want to build gcc-3.3.6? because I want to use it to build Linux Kernel 2.4.36. It was requested to build Linux Kernel 2.4.36 with the GCC version < 4.2. (please see: home/dingjun/build_cross_gcc/linux-2.4.36/include/linux/compiler.h:45:2: error: #error "GCC >= 4.2 miscompiles kernel 2.4, do not use it!" 45 | #error "GCC >= 4.2 miscompiles kernel 2.4, do not use it!") I tried several gcc version (<4.2) and almost each one has some errors. Could you some tell me which gcc(<4.2 version) source codes are 100% sure to be built without errors? Thanks & regards, Dingjun /***** an error occurred when building gcc-3.3.6************/ In file included from ./config.h:17, from f/proj.h:30, from f/com.c:83: ./tree.h:2244:55: note: expected ‘const char *’ but argument is of type ‘unsigned char *’ 2244 | extern tree build_string PARAMS ((int, const char *)); | ^~~~~~~~~~~~ ./../include/ansidecl.h:152:33: note: in definition of macro ‘PARAMS’ 152 | #define PARAMS(ARGS) ARGS | ^~~~ f/com.c: At top level: f/com.c:11079:1: error: conflicting types for ‘ffecom_gfrt_basictype’; have ‘ffeinfoBasictype(ffecomGfrt)’ 11079 | ffecom_gfrt_basictype (ffecomGfrt gfrt) | ^~~~~~~~~~~~~~~~~~~~~ In file included from f/com.c:124: f/com.h:236:17: note: previous declaration of ‘ffecom_gfrt_basictype’ with type ‘ffeinfoKindtype(ffecomGfrt)’ 236 | ffeinfoKindtype ffecom_gfrt_basictype (ffecomGfrt ix); | ^~~~~~~~~~~~~~~~~~~~~ f/com.c: In function ‘ffecom_init_0’: f/com.c:11624:28: warning: comparison between ‘ffeinfoKindtype’ and ‘enum <anonymous>’ [-Wenum-compare] 11624 | if (ffecom_pointer_kind_ == FFEINFO_basictypeNONE) | ^~ In file included from f/com.c:16573: ./gt-f-com.h: In function ‘gt_ggc_mx_lang_tree_node’: ./gt-f-com.h:65:7: warning: switch condition has boolean value [-Wswitch-bool] 65 | switch (TREE_CODE (&((*x)).generic) == IDENTIFIER_NODE) | ^~~~~~ f/com.c: In function ‘ffe_mark_addressable’: f/com.c:14300:9: warning: this statement may fall through [-Wimplicit-fallthrough=] 14300 | put_var_into_stack (x, /*rescan=*/true); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ f/com.c:14303:7: note: here 14303 | case FUNCTION_DECL: | ^~~~ f/com.c:14304:30: warning: this statement may fall through [-Wimplicit-fallthrough=] 14304 | TREE_ADDRESSABLE (x) = 1; f/com.c:14310:7: note: here 14310 | default: | ^~~~~~~ make[1]: *** [Makefile:735: f/com.o] Error 1 make[1]: Leaving directory '/home/dingjun/build_cross_gcc/gcc-3.3.6/gcc' make: *** [Makefile:1546: all-gcc] Error 2 Dingjun Chen | Software Developer [Geotech Airborne Geophysical Surveys] Geotech Ltd. dba Geotech Airborne | 270 INDUSTRIAL PKY S | AURORA ON CA | L4G 3T9 T: +1 905 841 5004 | Dingjun.Chen@xxxxxxxxxxxxxxxxxxx<mailto:Dingjun.Chen@xxxxxxxxxxxxxxxxxxx> | www.geotechairborne.com<www.geotech.ca> P Please consider the environment before printing this email This message may contain PRIVILEGED AND PROPRIETARY INFORMATION intended solely for the use of the addressee (s) named above.
