New submission from Lai, Yian:
I want to altinstall 3.6 with LTO+PGO optimizations, so:
./configure --enable-shared --enable-optimizations --prefix=$HOME/.local
LDFLAGS=-Wl,-rpath=$HOME/.local/lib
make
(./configure arguments refer to issue #27685)
But I get in trouble when running compiled python to generate posix vars:
...
gcc -pthread -shared -Wl,-rpath=/home/halfcoder/.local/lib -fprofile-generate
-Wl,--no-as-needed -o libpython3.so -Wl,-hlibpython3.so libpython3.6m.so
gcc -pthread -Wl,-rpath=/home/halfcoder/.local/lib -fprofile-generate -Xlinker
-export-dynamic -o python Programs/python.o -L. -lpython3.6m -lpthread -ldl
-lutil -lm
LD_LIBRARY_PATH=/home/halfcoder/.local/src/Python-3.6.0-optmiz ./python -E -S
-m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
echo "generate-posix-vars failed" ; \
rm -f ./pybuilddir.txt ; \
exit 1 ; \
fi
./python: symbol lookup error: ./python: undefined symbol:
__gcov_indirect_call_profiler
generate-posix-vars failed
make[2]: *** [pybuilddir.txt] Error 1
