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 --with-abi=lp64
%endif
Even by changing above two flags for different options. still i am not able to
rebuilt it. Here I am listing all combinations and error result what I have
tried for rebuilding gcc SRPM.
1. %ifarch riscv64
--with-arch=rv64g --with-multilib
Result: #error "rv32i-based targets are not supported"
2. %ifarch riscv64
--with-arch=rv64imafd --enable-multilib --with-multilib-list=lp64
Result:
unsupported --with-arch for --with-multilib-list
make[2]: *** [Makefile:4441: configure-stage1-gcc] Error 1
make[2]: Leaving directory
'/root/rpmbuild/BUILD/gcc-10.2.1-20201125/obj-riscv64-redhat-linux'
3. %ifarch riscv64
--with-arch=rv64imafd --enable-multilib --with-multilib-list=lp64d
Result:
unsupported --with-arch for --with-multilib-list
make[2]: *** [Makefile:4441: configure-stage1-gcc] Error 1
make[2]: Leaving directory
'/root/rpmbuild/BUILD/gcc-10.2.1-20201125/obj-riscv64-redhat-linux'
4. %ifarch riscv64
--with-arch=rv64g --with-abi=lp64d --with-multilib-list=lp64d
Result:
unsupported --with-arch for --with-multilib-list
make[2]: *** [Makefile:4441: configure-stage1-gcc] Error 1
5. %ifarch riscv64
--with-arch=rv64g --with-abi=lp64 --with-multilib-list=lp64
Result: unsupported --with-arch for --with-multilib-list
6. %ifarch riscv64
--with-arch=rv64g --enable-multilib
Result: #error "rv32i-based targets are not supported"
7. %ifarch riscv64
--with-arch=rv64g --with-abi=lp64
Result: #error "rv32i-based targets are not supported"
8. %ifarch riscv64
--with-arch=rv64g --with-multilib-generator="rv64ima-lp64--f"
Result: #error "rv32i-based targets are not supported"
9. %ifarch riscv64
--with-arch=rv64g --with-abi=lp64
--with-multilib-generator="rv64ima-lp64--f"
Result: error: #error "rv32i-based targets are not supported"
10. %ifarch riscv64
--with-arch=rv64g --enable-multilib
--with-multilib-generator="rv64ima-lp64--f"
Result: #error "rv32i-based targets are not supported"
Here very important observation I have noted. when I am giving below option
%ifarch riscv64
--with-arch=rv64g --disable-multilib
Here all library packages are going to /usr/lib folder path, but in-between
rebuilding process move commands are there, that are trying to move files from
/usr/lib64 path. But no file is there in /usr/lib64 path. all falied move
commads files are there in /usr/lib path.
Can anyone please spend some time on this issue and help me out for successfull
rebulding gcc SRPM. Please suggest perfect combination for sucessfull
rebuilding. I hope someone faced same problem before i think, thier expreince
will heplfull for me.
Thanks
Billa Surendra
