Hi, Since the recent gnulib update in gdb [1], gdbserver fail to build with a musl or uClibc-ng libc based toolchains with: x86_64-linux-musl-gcc -shared -fPIC -Wl,--no-undefined -D_LARGEFILE_SOURCE \ -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -I. -I. -I./../common \ -I./../regformats -I./.. -I./../../include -I./../gnulib/import \ -Ibuild-gnulib-gdbserver/import -Wall -Wpointer-arith -Wno-unused \ -Wunused-value -Wunused-function -Wno-switch -Wno-char-subscripts -Wempty-body \ -Wpointer-sign -Wmissing-prototypes -Wdeclaration-after-statement \ -Wmissing-parameter-type -Wold-style-declaration -Wold-style-definition \ -Wformat-nonliteral -Wno-missing-prototypes -DGDBSERVER -static-libstdc++ \ -static-libgcc -Wl,--dynamic-list=./proc-service.list -o libinproctrace.so \ ax-ipa.o tracepoint-ipa.o format-ipa.o utils-ipa.o regcache-ipa.o \ remote-utils-ipa.o common-utils-ipa.o tdesc-ipa.o print-utils-ipa.o \ rsp-low-ipa.o errors-ipa.o amd64-linux-ipa.o amd64-avx-linux-ipa.o \ amd64-avx512-linux-ipa.o amd64-mpx-linux-ipa.o linux-amd64-ipa.o -ldl -pthread tracepoint-ipa.o: In function `get_timestamp': tracepoint.c:(.text+0x147): undefined reference to `rpl_gettimeofday' This is during libinproctrace.so build. The issue seems related to gnulib gl_cv_func_gettimeofday_clobber check which was fixed for glibc toolchain [2]. The default assumption while cross-compiling seems wrong since it set REPLACE_GETTIMEOFDAY and replace gettimeofday by rpl_gettimeofday when *-gnu* suffix is missing.

Is this still an issue? If you know whether/when this was fixed in gnulib upstream, please update this bug so we can consider updating our gnulib copy to a newer revision.
Hi, This issue is not fixed in gnulib itself, but was fixed in Buildroot by using gl_cv_func_gettimeofday_clobber=no to not use rpl_gettimeofday, assuming musl and uClibc have a properly working gettimeofday implementation (see [1]). This fix was suggested by the musl FAQ [2].
