Thus the compilation failed with a message like : /tmp/ccEugNg3.s: Assembler messages: /tmp/ccEugNg3.s:889: Error: junk at end of line, first unrecognized character is `,' REASON : .section .gnu.linkonce.t.__tf9type_info,"ax",@progbits ^^^^ The `@` is the comment symbol for ARM assembler. So the line expands to "[...], <nothing>", The , at the end causes the error and arm-elf-as complains and stops the compilation process To fix this, GCC must not use `@` but `%` instead when targeting ARM. The place to patch is in gcc-2.95.3/gcc/config/arm/unknown-elf.h Thanks for your support Andreas ============================================ --- gcc-2.95.3-core/gcc/config/arm/unknown-elf.h 1999-04-09 06:07:56.000000000 -0700 +++ ./unknown-elf.h 2004-06-30 11:51:16.000000000 -0700 @@ -100,7 +100,7 @@ #define ASM_OUTPUT_SECTION_NAME(STREAM, DECL, NAME, RELOC) \ do { \ if ((DECL) && TREE_CODE (DECL) == FUNCTION_DECL) \ - fprintf (STREAM, "\t.section %s,\"ax\",@progbits\n", (NAME)); \ + fprintf (STREAM, "\t.section %s,\"ax\",%%progbits\n", (NAME)); \ else if ((DECL) && DECL_READONLY_SECTION (DECL, RELOC)) \ fprintf (STREAM, "\t.section %s,\"a\"\n", (NAME)); \ else \ == Andreas ------ Want more information?
