Bug ID: 22941
Summary: binutils build fails if intl/parser.y is newer than
intl/parser.c
Product: binutils
Version: 2.31 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: rprichard at google dot com
Target Milestone: ---
binutils has the same non-deterministic build problem that was reported in
https://sourceware.org/bugzilla/show_bug.cgi?id=22432. (Aside: various other
projects appear to have the same pair of files, e.g. gdb, gcc, e2fsprogs, ...)
When I build binutils for Linux, it uses gettext from libc, but when I
cross-compile for Windows, it instead used its bundled libintl. If I check out
binutils source on a normal Linux desktop, the intl/plural.c and intl/plural.y
typically have equal mtimes and ctimes, so the build system uses the
intl/plural.c file (generated by Bison 1.35) and the build succeeds.
If I instead use a WSL (Windows-Subsystem-for-Linux) environment, the
intl/plural.y is typically newer than intl/plural.c (slower filesystem?), and
the build system regenerates plural.c (using e.g. Bison 3.0.4). With the
regenerated file, the build fails.
Build errors:
bison -y --name-prefix=__gettext --output plural.c ../../intl/plural.y

binutils already requires bison to build, so it seems sensible to fix this
issue the same way that glibc was already fixed:
rprichard@cashew:~/android/binutils-gdb$ for f in $(find . -name '*.y'); do
echo -- $f; find . -name $(basename ${f%.y}.c); done

Steps to cross-compile binutils:
On a Debian system, install the mingw-w64 package. This provide a GCC toolchain
with the triple x86_64-w64-mingw32 (e.g. x86_64-w64-mingw32-gcc)
Run these commands:
/path/to/configure --host=x86_64-w64-mingw32
make
