build: add "set -eu" to version script generation It turns out that on certain systems like FreeBSD, c++filt is not installed by default. It's basically OK if we fail the build in that case, but what's really not OK is for the build to continue and generate bad binaries. 2015-07-27 20:42:32 +02:00			`set -eu`
libnotmuch: export Xapian typeinfo symbols The lack of such exporting seems to cause problems catching exceptions, as suggested by http://gcc.gnu.org/wiki/Visibility This manifested in the symbol-hiding test failing when notmuch was compile with gcc 4.4.5. On i386, this further manifested as notmuch new failing to run (crashing with an uncaught exception on first run). 2011-07-16 20:59:44 +02:00

lib/gen-version-script.sh: replace --defined argument to nm with awk OpenBSD nm apparently doesn't support --defined. The awk condition is based on the assumption that all defined symbols have some hex number in the first column. Thanks to Matthias Guedemann reporting the problem, and an earlier version of this patch. 2011-09-05 04:50:36 +02:00			`nm $* \| awk '$1 ~ "^[0-9a-fA-F][0-9a-fA-F]$" && $3 ~ "Xapian.Error" {print $3}' \| sort \| uniq \| \`

re-enable notmuch.sym generation using POSIX sed Unfortunately Robin Green's patch 52e4dedf9aa was lost when I created gen-version-script.sh. This merges his changes manually into that script. It turns out tabs seem not needed in version script files, so I simplified a bit and removed the printf. Thanks to Alexander Botero-Lowry for help and testing. 2011-08-21 21:45:00 +02:00			`sed -n 's/^[[:space:]]\(notmuch_[a-z_]\)[[:space:]](./ \1;/p' $HEADER`
