Yes, I already tried to fix this one in the past but iirc it caused problem with some other targets. For musl you probably want to conditionally revert this patch: https://git.savannah.gnu.org/cgit/screen.git/commit/?h=screen-v4&id=2e2410a668be96bcd64afbba2fd601c237f5a68e Reason for this is that v4 (screen-v4 git branch) has so much #ifdeffery that no matter what you do it breaks, so it's unlikely to be fixed in next v4 release. I could take another look at fixing it in v4, but quite frankly I think my limited time is better spend at working towards making v5 a reality, for v5 I did a lot of cleaning up and tried to depend on posix compatibility almost everywhere to avoid such problems and removed most of those #ifdefs, which seems to work quite well. Also it's not caused by gcc-8 but by using musl, so no need to block gcc-8, I have same result with gcc-6 when trying to build 4.6.2. utmp.c: In function ‘getlogin’: utmp.c:850:15: error: storage size of ‘u’ isn’t known struct utmp u; ^ utmp.c:860:38: error: invalid application of ‘sizeof’ to incomplete type ‘struct utmp’ while (read(fd, (char *)&u, sizeof(struct utmp)) == sizeof(struct utmp)) ^~~~~~ utmp.c:860:62: error: invalid application of ‘sizeof’ to incomplete type ‘struct utmp’ while (read(fd, (char *)&u, sizeof(struct utmp)) == sizeof(struct utmp)) ^~~~~~ utmp.c: At top level: utmp.c:881:1: error: conflicting types for ‘xpututline’ xpututline(u) ^~~~~~~~~~ utmp.c:98:21: note: previous declaration of ‘xpututline’ was here static struct utmp *xpututline __P((struct utmp *utmp)); ^~~~~~~~~~ utmp.c: In function ‘xpututline’: utmp.c:885:13: warning: passing argument 1 of ‘pututline’ from incompatible pointer type [-Wincompatible-pointer-types] pututline(u); ^ In file included from os.h:265:0, from screen.h:30, from utmp.c:34: /usr/include/utmp.h:32:14: note: expected ‘const struct utmpx *’ but argument is of type ‘struct utmp *’ struct utmp *pututline(const struct utmp *); ^~~~~~~~~ utmp.c:887:18: warning: passing argument 1 of ‘getutline’ from incompatible pointer type [-Wincompatible-pointer-types] u2 = getutline(u); ^ In file included from os.h:265:0, from screen.h:30, from utmp.c:34: /usr/include/utmp.h:31:14: note: expected ‘const struct utmpx *’ but argument is of type ‘struct utmp *’ struct utmp *getutline(const struct utmp *); ^~~~~~~~~ utmp.c:887:6: warning: assignment from incompatible pointer type [-Wincompatible-pointer-types] u2 = getutline(u); ^ utmp.c:889:13: error: dereferencing pointer to incomplete type ‘struct utmp’ return u->ut_type == DEAD_PROCESS ? u : 0; ^~ utmp.c: At top level: utmp.c:98:21: warning: ‘xpututline’ used but never defined static struct utmp *xpututline __P((struct utmp *utmp)); ^~~~~~~~~~ make: *** [Makefile:82: utmp.o] Error 1 make: *** Waiting for unfinished jobs.... * ERROR: app-misc/screen-4.6.2::gentoo failed (compile phase): * emake failed * * If you need support, post the output of `emerge --info '=app-misc/screen-4.6.2::gentoo'`, * the complete build log and the output of `emerge -pqv '=app-misc/screen-4.6.2::gentoo'`. * The complete build log is located at '/var/tmp/portage/app-misc/screen-4.6.2/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/app-misc/screen-4.6.2/temp/environment'. * Working directory: '/var/tmp/portage/app-misc/screen-4.6.2/work/screen-4.6.2' * S: '/var/tmp/portage/app-misc/screen-4.6.2/work/screen-4.6.2' >>> Failed to emerge app-misc/screen-4.6.2, Log file: >>> '/var/tmp/portage/app-misc/screen-4.6.2/temp/build.log' * Messages for package app-misc/screen-4.6.2: * ERROR: app-misc/screen-4.6.2::gentoo failed (compile phase): * emake failed * * If you need support, post the output of `emerge --info '=app-misc/screen-4.6.2::gentoo'`, * the complete build log and the output of `emerge -pqv '=app-misc/screen-4.6.2::gentoo'`. * The complete build log is located at '/var/tmp/portage/app-misc/screen-4.6.2/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/app-misc/screen-4.6.2/temp/environment'. * Working directory: '/var/tmp/portage/app-misc/screen-4.6.2/work/screen-4.6.2' * S: '/var/tmp/portage/app-misc/screen-4.6.2/work/screen-4.6.2' ssh # gcc --version gcc (Gentoo Hardened 6.4.0-r1 p1.3) 6.4.0 Copyright (C) 2017 Free Software Foundation, Inc.

Created attachment 537788 [details] log of successful build with sys-devel/gcc-8.1.0-r3 I have no problem building app-misc/srceen-4.6.2 with sys-devel/gcc-8.1.0-r3 on amd64. Not sure why it works for me but not for the OP. Maybe because I have USE='-pam'? Just a wild, unsubstantiated guess.

I will test if reverting that patch will work as a workaround for the moment.
Amadeusz, I have tested the patch you suggested, it results in redefinitions. I will wait for you to make the release from branch master which is working.
Is this still a problem with gcc-8.2.0?
(In reply to tt_1 from comment #6) > Is this still a problem with gcc-8.2.0? I just rebuilt screen-4.6.2-r1 on with gcc-8.2.0-r6 without problem.
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.0.6&id=8f84f7daabb2fddfc5f81e9257e8c465b2a0caef after reverting as chithead suggested it compiles fine. anarchy@bull ~ $ pkg-config libelf --libs -lelf which is what the default would be with the revert.
I can no longer produce the failure so will close for now.
