Hi, There is the following build issue with gdb 8.1.1 and 8.2: /opt/x86-core2--musl--bleeding-edge-2018.09-1/bin/i686-buildroot-linux-musl-g++ -shared -fPIC -Wl,--soname=libinproctrace.so -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 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Wall -Wpointer-arith -Wno-unused -Wunused-value -Wunused-function -Wno-switch -Wno-char-subscripts -Wempty-body -Wunused-but-set-parameter -Wunused-but-set-variable -Wno-sign-compare -Wno-narrowing -Wno-error=maybe-uninitialized -DGDBSERVER \ -Wl,--dynamic-list=./proc-service.list -o libinproctrace.so ax-ipa.o common-utils-ipa.o errors-ipa.o format-ipa.o print-utils-ipa.o regcache-ipa.o remote-utils-ipa.o rsp-low-ipa.o tdesc-ipa.o tracepoint-ipa.o utils-ipa.o vec-ipa.o linux-i386-ipa.o linux-x86-tdesc-ipa.o arch/i386-ipa.o -ldl -pthread /opt/x86-core2--musl--bleeding-edge-2018.09-1/lib/gcc/i686-buildroot-linux-musl/8.2.0/../../../../i686-buildroot-linux-musl/bin/ld: common-utils-ipa.o: in function `is_regular_file(char const*, int*)': common-utils.c:(.text+0x695): undefined reference to `rpl_stat' collect2: error: ld returned 1 exit status Makefile:413: recipe for target 'libinproctrace.so' failed make[1]: *** [libinproctrace.so] Error 1 The issue is related to this patch: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=2441702a72f324e41a1624dc042b334f375e2d81 See the discussion on the mailing list: https://sourceware.org/ml/gdb-patches/2018-09/msg00306.html The patch provided by Sergio Durigan Junior should be backported to gdb 8.1.x and 8.2.x stable branch: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=3c025cfe5efc44eb4dfb03b53dca28e75096dd1e Best regards, Romain
The gdb-8.2-branch branch has been updated by Sergio Durigan Junior <sergiodj@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=5de69bdbd0bbd7941b4cd93d4571f5e22cdb28be commit 5de69bdbd0bbd7941b4cd93d4571f5e22cdb28be Author: Sergio Durigan Junior <sergiodj@redhat.com> Date: Sat Sep 15 16:40:13 2018 -0400 Move 'is_regular_file' from common-utils.c to filestuff.c There is no reason for 'is_regular_file' to be in common-utils.c; it belongs to 'filestuff.c'. This commit moves the function definition and its prototype to the appropriate files. The motivation behind this move is a failure that happens on certain cross-compilation environments when compiling the IPA library, due to the way gnulib probes the need for a 'stat' call replacement. Because configure checks when cross-compiling are more limited, gnulib decides that it needs to substitute the 'stat' calls its own 'rpl_stat'; however, the IPA library doesn't link with gnulib, which leads to an error when compiling 'common-utils.c': ... /opt/x86-core2--musl--bleeding-edge-2018.09-1/bin/i686-buildroot-linux-musl-g++ -shared -fPIC -Wl,--soname=libinproctrace.so -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 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Wall -Wpointer-arith -Wno-unused -Wunused-value -Wunused-function -Wno-switch -Wno-char-subscripts -Wempty-body -Wunused-but-set-parameter -Wunused-but-set-variable -Wno-sign-compare -Wno-narrowing -Wno-error=maybe-uninitialized -DGDBSERVER \ -Wl,--dynamic-list=./proc-service.list -o libinproctrace.so ax-ipa.o common-utils-ipa.o errors-ipa.o format-ipa.o print-utils-ipa.o regcache-ipa.o remote-utils-ipa.o rsp-low-ipa.o tdesc-ipa.o tracepoint-ipa.o utils-ipa.o vec-ipa.o linux-i386-ipa.o linux-x86-tdesc-ipa.o arch/i386-ipa.o -ldl -pthread /opt/x86-core2--musl--bleeding-edge-2018.09-1/lib/gcc/i686-buildroot-linux-musl/8.2.0/../../../../i686-buildroot-linux-musl/bin/ld: common-utils-ipa.o: in function `is_regular_file(char const*, int*)': common-utils.c:(.text+0x695): undefined reference to `rpl_stat' collect2: error: ld returned 1 exit status Makefile:413: recipe for target 'libinproctrace.so' failed make[1]: *** [libinproctrace.so] Error 1 ... More details can also be found at: https://sourceware.org/ml/gdb-patches/2018-09/msg00304.html The most simple fix for this problem is to move 'is_regular_file' to 'filestuff.c', which is not used by IPA. This ends up making the files more logically organized as well, since 'is_regular_file' is a file operation. No regressions found. gdb/ChangeLog: 2018-09-15 Sergio Durigan Junior <sergiodj@redhat.com> PR gdb/23663 * common/common-utils.c: Don't include '<sys/stat.h>'.
