When xz was compiled before, gdb will use it as optional dependency:
$ output/host/usr/bin/i586-buildroot-linux-uclibc-readelf -a output/target/usr/bin/gdb | grep NEEDED

Hello Thomas, Bernd, all,
for some reason gdb fails to build with xz and expat support at the same
time when using an external toolchain.
This is how the problem is shown:
checking for liblzma... no
configure: error: missing liblzma for --with-lzma
Try this defconfig if you want to reproduce the problem:
BR2_x86_64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_PACKAGE_XZ=y
BR2_PACKAGE_GDB=y
BR2_PACKAGE_GDB_DEBUGGER=y
BR2_PACKAGE_EXPAT=y
Using the above defconfig, the error in the gdb/config.log will look
like this:
configure:13241: checking whether to use lzma
configure:13243: result: yes
configure:13657: checking for liblzma
configure:13678: /br/output/host/usr/bin/i686-pc-linux-gnu-gcc -o
conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64 -Os
-I/br/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/include
-static-libstdc++ -static-libgcc conftest.c -ldl -ldl -lncurses -lm
-ldl /usr/lib/liblzma.so >&5
/lib64/liblzma.so.5: undefined reference to `clock_gettime at GLIBC_2.17'
collect2: error: ld returned 1 exit status
You can also use this defconfig to reproduce the problem for MIPS:
BR2_mips=y
BR2_mips_32r2=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_PACKAGE_XZ=y
BR2_PACKAGE_GDB=y
BR2_PACKAGE_GDB_DEBUGGER=y
BR2_PACKAGE_EXPAT=y
In that case the error will look like this:
configure:13241: checking whether to use lzma
configure:13243: result: yes
configure:13657: checking for liblzma
configure:13678: /br/output/host/usr/bin/mips-linux-gnu-gcc -o conftest
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os
-I/br/output/host/usr/mips-buildroot-linux-gnu/sysroot/usr/include
-static-libstdc++ -static-libgcc conftest.c -ldl -ldl -lncurses -lm
-ldl /usr/lib/liblzma.so >&5
/br/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/5.2.0/../../../../mips-linux-gnu/bin/ld:
skipping incompatible /lib64/liblzma.so.5 when searching for
/lib64/liblzma.so.5
/br/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/5.2.0/../../../../mips-linux-gnu/bin/ld:
cannot find /lib64/liblzma.so.5
collect2: error: ld returned 1 exit status
You can also use this defconfig to reproduce the problem for ARM:
BR2_arm=y
BR2_cortex_a7=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_PACKAGE_XZ=y
BR2_PACKAGE_GDB=y
BR2_PACKAGE_GDB_DEBUGGER=y
BR2_PACKAGE_EXPAT=y
In that case the error will look like this:
configure:13241: checking whether to use lzma
configure:13243: result: yes
configure:13657: checking for liblzma
configure:13678: /br/output/host/usr/bin/arm-linux-gnueabihf-gcc -o
conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64 -Os
-I/br/output/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include
-static-libstdc++ -static-libgcc conftest.c -ldl -ldl -lncurses -lm
-ldl /usr/lib/liblzma.so >&5
/lib64/liblzma.so.5: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
Regards,
Vincent.
