Hello I have a problem with a big Data.fs in Zope(2.5.1/Python-2.1.3) and large file support on linux. I tried to recompile Python with the following steps: export CC='gcc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64' rm config.cache ./configure --prefix=/export/home/www/medizin/local2 --with-large-file-support --with-thread --with-threads --with-lfs --with-large-file (it's a privat installation of the user "medizin", not system wide) make clean make make install On our test server (Debian 3.0 Woody) everything works fine, and "test_largefile.py" says: <quote> create large file via seek (may be sparse file) ... 2500000001L =?= 2500000001L ... yes check file size with os.fstat check file size with os.stat 2500000001L =?= 2500000001L ... yes play around with seek() and read() with the built largefile 0L =?= 0 ... yes '\x00' =?= '\x00' ... yes 1L =?= 1 ... yes 0L =?= 0 ... yes 0L =?= 0 ... yes 42L =?= 42 ... yes 42L =?= 42 ... yes 84L =?= 84 ... yes 84L =?= 84 ... yes 2500000001L =?= 2500000001L ... yes 2499999991L =?= 2499999991L ... yes 0L =?= 0 ... yes 2500000000L =?= 2500000000L ... yes 'a' =?= 'a' ... yes play around with os.lseek() with the built largefile 0L =?= 0 ... yes 42L =?= 42 ... yes 84L =?= 84 ... yes 84L =?= 84 ... yes 2500000001L =?= 2500000001L ... yes 2499999991L =?= 2499999991L ... yes 0L =?= 0 ... yes 2500000000L =?= 2500000000L ... yes 'a' =?= 'a' ... yes @test exists: 0 </quote> This seems to be OK. But the same procedure on our live server (RedHat 7.3 Valhalla) says: ... make install => make: *** [libinstall] Error 1 And "test_largefile.py" says: <quote> Traceback (most recent call last): File "test_largefile.py", line 22, in ? raise test_support.TestSkipped, \ test_support.TestSkipped: platform does not have largefile support </quote> The first thing I thought about was that I can not call "make install" while Zope (or any python process) is still running. So I stopped Zope and tried "make install" again, but with the same error message. Note that the old Python version (2.1.3 without large file support) was compiled by me on the same computer (RH 7.3), with no problems. Can anybody help me? Any hints?
