Package: pmake
Version: 1.111-1
Severity: normal
In parallel mode with a Makefile using VPATH, when a target has several
commands to update it, a change of directory done in an earlier command
is mistakenly carried over to later commands.
Reproduce like this in an empty directory:
mkdir src src/sub build
echo hi > src/sub/file.in
tr X '\t' >build/Makefile <<'EOF'
srcdir = ../src
VPATH = ../src
$(srcdir)/sub/file: $(srcdir)/sub/file.in FORCE
Xcd $(srcdir)/sub && cat file.in
Xpwd; echo stamp > $@
FORCE:
EOF
cd build
pmake -j2
Output:
| --- ../src/sub/file ---
| cd ../src/sub && cat file.in
| hi
| pwd; echo stamp > ../src/sub/file
| /tmp/t/src/sub
| sh: line 5: ../src/sub/file: No such file or directory
| *** [../src/sub/file] Error code 1
| 1 error
|
| pmake: stopped in /tmp/t/build
The output of 'pwd' shows that the second command line starts off in the
wrong directory.
Expected output ('make -j2' or 'pmake' without -j):
[...]
| cd ../src/sub && cat file.in
| hi
| pwd; echo stamp > ../src/sub/file
| /tmp/t/build
This may be exposed for example when building Libtool with pmake -j2,
when the rebuild rule for $(srcdir)/libltdl/stamp-mk triggers.
I tried this on NetBSD 4.99.70, its make has the problem as well.
If you have access to newer versions, can you try it out? Do you
have contacts to upstream to report this or should I report it
otherwise?
Cheers, and thanks for maintaining Debian,
