OpenWrt GCC 8.3.0 r11655-a283b17 update GCC version can solve it.
Created attachment 126374 [details] Fix OpenWRT build [WIP] Hi, this patch fixes the "msa" issue with "mipsel-openwrt-linux-uclibc-gcc.bin (OpenWrt/Linaro GCC 4.8-2014.04 r47072) 4.8.3" Please let me know is it helpful. However, there is another problem during linkage of vgdb: /work/toolchain/iDetect-839d28effb806ce37c6c85b0da3de22bd6255450/OpenWrt-Toolchain-ramips-mt7688_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/bin/../lib/gcc/mipsel-openwrt-linux-uclibc/4.8.3/../../../../mipsel-openwrt-linux-uclibc/lib/libpthread.so.0: undefined reference to `dlopen' /work/toolchain/iDetect-839d28effb806ce37c6c85b0da3de22bd6255450/OpenWrt-Toolchain-ramips-mt7688_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/bin/../lib/gcc/mipsel-openwrt-linux-uclibc/4.8.3/../../../../mipsel-openwrt-linux-uclibc/lib/libpthread.so.0: undefined reference to `dlsym' collect2: error: ld returned 1 exit status Makefile:2883: recipe for target 'vgdb' failed It seems that dlopen/dlsym functions are missing in provided version of uClibc. Have you ever encountered this situation (using this particular version of toolchain) ? Best wishes, Aleksandar
I would suggest that this issue gets resolved by upgrading toolchain version, if possible.
