Hi everyone,
Can anyone explain what is the difference between the following two
approaches for rebuilding GCC SRPM on RISC-V Fedora image. Here I have
changed the gcc.spec file.
*Method-1:*
%ifarch riscv64
--with-arch=rv64g --enable-multilib --with-multilib-list=lp64
%endif
*Result:*
#error
Is there any way to proceed for rebuilt gcc SRPM without C support ?

Hi Billa,
I am not sure if compressed instruction support can be disabled, but
it appears to me that --with-arch= should be rv32gc or rv64gc for
multilib. It is implemented in the gcc/config.gcc file.
Florian mentioned that there is no glibc without compressed
instruction support. Perhaps, gcc
Dear all,
From last 10 days I am struggling to rebuilding gcc-10.2.1-9.fc33.src.rpm
SRPM on RISC-V Fedora image. Here I am planning to rebuilt this SRPM without
compressed instruction support. Following changed I have done on gcc.spec file.
%ifarch riscv64
--with-arch=rv64g

As far as I understand it, there is no glibc port for RISC-V without
compressed instruction support. Presumably the GCC default reflects
this.
Hi,
I think "--with-arch=" should be "rv64g" for gcc without compressed
instruction support, because the default is RV64GC[0].
If you want to rebuild gcc for compiling linux applications, I think
"--with-newlib" should be removed . If you want to rebuild gcc for
compiling both 64-bit/32-bit
Dear All,
I am trying to rebuild gcc SRPM for RISC-V architecture (without compressed
instruction support). Can any one please give some clarity, about which
combination is correct for native compiler without compressed instruction
support.
These are the combinations:
1. --with-arch=rv64g
15 matches
