Hello, I'm trying to use gcc with newlib for arm926ej-s development, but I'm facing problems with multilib. I'd like to force gcc to compile with -msoft-float but, newlib and libgcc are still built with VFP instructions. I'm getting these errors from linker $ arm-unknown-elf-gcc -mthumb-interwork -mlittle-endian -mfloat-abi=soft -mtune=arm926ej-s -march=armv5te test.c -o test.o e:/_dev/gcc/install/bin/../lib/gcc/arm-unknown-elf/4.5.2/../../../../arm-unknown-elf/bin/ld.exe: error: C:\DOCUME~1\POHANK~1.JAB\LOCALS~1\Temp\ccsKkuU3.o uses VFP instructions, whereas test.o does not e:/_dev/gcc/install/bin/../lib/gcc/arm-unknown-elf/4.5.2/../../../../arm-unknown-elf/bin/ld.exe: failed to merge target specific data of file C:\DOCUME~1\POHANK~1.JAB\LOCALS~1\Temp\ccsKkuU3.o collect2: ld returned 1 exit status arm-unknown-elf-gcc -print-multi-lib returns .;@msoft-float@mfloat-abi=soft thumb;@mthumb@msoft-float@mfloat-abi=soft interwork;@mthumb-interwork@msoft-float@mfloat-abi=soft thumb/interwork;@mthumb@mthumb-interwork@msoft-float@mfloat-abi=soft Build settings $ arm-unknown-elf-gcc -v Using built-in specs.

I build them in combined directory with configuration described above. I also tried to alter t-arm-elf file, but unfortunately I'm not very wise from the description in Target Makefile Fragments. I know I should use arm-eabi instead of arm-elf, but I have to stay with arm-elf due to compatibility demands. best regards Jan -- View this message in context: http://old.nabble.com/Multilib-problem-with-arm-elf-tp31096676p31096676.html Sent from the gcc - Help mailing list archive at Nabble.com.
