Subject: [PATCH] Fix getopt linking error with musl-libc
|
||
|
|
|
||
|
|
The buildroot project, to which the sscep application was added, has
|
||
|
|
configurations that raise the following linking error:
|
||
|
|
buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/i586-buildroot-linux-musl/9.3.0/../../../../i586-buildroot-linux-musl/bin/ld: buildroot/output/host/i586-buildroot-linux-musl/sysroot/lib/libc.a(getopt.o): in function `getopt':
|
||
|
|
getopt.c:(.text.getopt+0x0): multiple definition of `getopt'; src/getopt.o:getopt.c:(.text+0x0): first defined here
|
||
|
|
buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/i586-buildroot-linux-musl/9.3.0/../../../../i586-buildroot-linux-musl/bin/ld: buildroot/output/host/i586-buildroot-linux-musl/sysroot/lib/libc.a(getopt.o):(.data.optind+0x0): multiple definition of `optind'; src/getopt.o:(.data+0x0): first defined here
|
||
|
|
collect2: error: ld returned 1 exit status
|
||
|
|
|
||
|
|
The commit 65561b53344b8 ("Fix getopt linking error") actually fixed the
|
||
|
|
linking error only for uclibc, but not for musl-libc. The patch fixes
|
||
|
|
the error for both uclibc and musl-libc.
