Bug ID: 23731
Summary: Building from git issues Ubuntu
Product: binutils
Version: 2.32 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: jg at jguk dot org
Target Milestone: ---
1)
Is there a way for ./configure to check for "makeinfo" "bison" "flex" commands
first? I just get it bailing out at the end half way through a build. I imagine
everyone else on Ubuntu sees the same as me... Impacts new developers getting
started
gcc -c -I. -I. -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow
-Wstack-usage=262144 -Werror -I./../zlib -g -O2 -Wno-error ./syslex_wrap.c
./syslex_wrap.c:25:10: fatal error: syslex.c: No such file or directory
#include "syslex.c"
^~~~~~~~~~
compilation terminated.
As bison, flex, makeinfo commands a really needed, and they mess with the files
generated which must be cleaned... could these be checked up front?
2) After "bison" and "flex" I saw this error:
I got this error:
configure: loading cache ./config.cache
configure: error: `YACC' has changed since the previous run:
configure: former value: `/home/jonny/code/binutils-gdb/missing bison -y'
configure: current value: `bison -y'
configure: error: in `/home/jonny/code/binutils-gdb/binutils':
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm ./config.cache' and start
over
Makefile:3527: recipe for target 'configure-binutils' failed
make[1]: *** [configure-binutils] Error 1
make[1]: Leaving directory '/home/jonny/code/binutils-gdb'
Makefile:849: recipe for target 'all' failed
make: *** [all] Error 2
Even the following commands did not clear it:
make distclean
./configure --program-prefix=dev
I'm 20 mins in.. and still no working build.
3)
I saw some warnings wizz past from -Wmaybe-uninitialized
CXX macrotab.o
In file included from infrun.c:26:0:
inferior.h: In function ‘void handle_vfork_child_exec_or_exit(int)’:

CXX main.o
Also i noticed the build stopped once after "make -j16", but then "make" on its
own, did a lot more compiling for several minutes... could be a build race
condition.
