python - Building and running llvm-py on Mac OS X -

i trying build llvm-py on mac os x.

this tried do, needed download 11vm-2.7, , readme file has comment: create sure '--enable-pic' passed llvm's 'configure'

download llvm 2.7. build llvm 2.7: run ./configure --prefix=llvm_directory --enable-pic download llvm-py 0.6. build llvm-py 0.6: run python setup.py build --llvm-config=llvm_directory/bin/llvm-config

everything compiles without errors, when tried run test file, got error message.

importerror: 'dlopen(/library/python/2.7/site-packages/llvm/_core.so, 2): symbol not found: __ztvn4llvm16extractvalueinste\n referenced from: /library/python/2.7/site-packages/llvm/_core.so\n expected in: flat namespace\n in /library/python/2.7/site-packages/llvm/_core.so'

the message error seems there missing function "llvmextractvalueinst" flat namemspace issue. what's wrong this?

in llvm 2.7, makefile.rules has line

sharedlinkoptions=-wl,-flat_namespace -wl,-undefined -wl,suppress \ -dynamiclib

i tried remove flat_namespace, got compilation error.

added

following locojay's answer, build brew , llvmpy.

export requires_rtti=1 brew install llvm --rtti sudo pip install git+https://github.com/llvmpy/llvmpy

however, when tried execute examples in test directory, still got different kind of error-

test> python example.py traceback (most recent phone call last): file "example.py", line 4, in <module> llvm import * file "/library/python/2.7/site-packages/llvm/__init__.py", line 11, in <module> llvm import _core importerror: dlopen(/library/python/2.7/site-packages/llvm/_core.so, 2): symbol not found: __zn4llvm10datalayout2ide referenced from: /library/python/2.7/site-packages/llvm/_core.so expected in: flat namespace in /library/python/2.7/site-packages/llvm/_core.so

this result when run otool -l /library/python/2.7/site-packages/llvm/_core.so

/library/python/2.7/site-packages/llvm/_core.so: /usr/lib/libsystem.b.dylib (compatibility version 1.0.0, current version 159.1.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)

have @ docs of llvmpy

for llvm 3.2, create sure environment variable requires_rtti=1 defined when running make. otherwise, may see "undefined symbol: _ztin4llvm24passregistrationlistenere". please refer http://llvm.org/docs/packaging.html#c-features details.

so me worked

export requires_rtti=1 brew install llvm --rtti pip install git+https://github.com/llvmpy/llvmpy

i guess 1 can give anaconda seek in worst case....

python osx build llvm llvm-py

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
