Configure can't find readline, zlib
by Nigel Gilbert 03 Dec '04

03 Dec '04

I am trying to do an installation from source of PostgreSQL into Suse 9.2 Professional. This is the first thing I've done with this distro. Configure fails, reporting that it cannot find the readline library, although it seems to be present in /lib Running ./configure as root, I get: checking for shmget in -lcygipc... no checking for readline... no configure: error: readline library not found If you have readline already installed, see config.log for details on the failure. It is possible the compiler isn't looking in the proper directory. .... However, a readline library appears to be present in /lib: # find / -name libreadline.so.5 -print /lib/libreadline.so.5 and is reported by ldconfig: # ldconfig -p | grep readline libreadline.so.5 (libc6) => /lib/libreadline.so.5 libguilereadline-v-12.so.12 (libc6) => /usr/lib/libguilereadline-v-12.so.12 libguilereadline-v-12.so (libc6) => /usr/lib/libguilereadline-v-12.so As a check, I explicitly specified to configure the libraries to search: # ./configure --with-libraries=/lib:/usr/lib but it fails in just the same way. I then told configure to ignore readline, and it continue but failed to find zlib in a similar way, although this too seems to be present in /usr/lib I must be doing something stupid - but what? [Note: I have to install from source because after this is working, I need to install an optional contrib to extend PostgeSQL to deal with spatial data, and this will only install into the source tree]. Thanks for your advice!

porting problems ....
by William A. Mahaffey III 02 Dec '04

02 Dec '04

.... I am trying to port some code (a Motif CAD/Grid-generator) from SGI to my SuSE 8.2 Linux box. Everything is coming fairly smoothly (actually DAMN smooth), except for 1 thing. The code is mostly C, with some leaf-FORTRAN. I use malloc/realloc & free to allocate & free mamory. I have found several places where I was calling free repeatedly with the same pointer (slides by on SGI, bombs under Linux) & corrected all of them so far. I have fixed all the simple/silly stuff (I think) & now need to go a bit deeper. I tried activating the documented memory debugging using '#define MALLOC_CHECK_' in my program main, but I get no diagnostics or core dump, just execution which gets to a specific line & hangs. I have also tried the mtrace facility, but just get mention of 3 hex addresses where memory is free'd that wasn't alloc'd. I think I am screwing something else up earlier, but can't get a core dump or any diagnostics to help me out. SGI has a nice & very handy memory debugger (malloc (3X)) which can be compiled in & activated at runtime as needed, ignored otherwise. I haven't found any such thing (yet) under Linux. My question is how do I get Linux to either dump core or give me some diagnostics (at every call to malloc or free, like SGI ;-) ) so I can find my more subtle screwups & fix them ? TIA

TIA You could try electric fence (probably on your distro. Try 'man efence'), NJAMD (Not Just Another Malloc Debugger), or google for something similar. Also, compiling it with the -g option (Assuming gcc), and run it through gdb. -Chris Kwasneski Software Engineer YPG, AZ

Eclipse crashes on Suse 9.2
by David van Coevorden 24 Nov '04

24 Nov '04

Hi I installed a fresh Suse Professional 9.2, with Eclipse. However it crashes regularly when it should not. E.g. when trying to open the CVS perspective, or when trying to adapt the font in the preferences.. I saw a post earlier in the german speaking list of someone having the same problem. Does anyone know of a solution, cause?? I paste a summary log of the errors below... -- David van Coevorden Stoutenburg 8 1121 GG Landsmeer (E) davaco(a)gmail.com (M) 06 250 30 653 (T) 020 64 70864 An unexpected exception has been detected in native code outside the VM.

posix named semaphores
by Joe Georger 17 Nov '04

17 Nov '04

I'm running Suse 9.0 AMD64 w/kernel 2.4.21-149. I get sem_open error for /mysem: Function not implemented when I try to create a posix named semaphore. However it does work on RH9 IA32 kernel 2.4.20-30.9 as well as under Suse 9.1 AMD64 kernel 2.6.5-7.95-smp. Is there an AMD64 2.4 kernel that would support this? Or do I have to go to 2.6? Thanks, Joe

RE: [suse-programming-e] Cannot run compiled programs from GCC -- SuSE 9.2
by Calkins, Dennis 17 Nov '04

Typically that means that the a.out created doesn't have the EXECUTE permission turned on. You forget that you speciifed -c ( compile only - no link ) along with -o a.out so you only compile to an object file and it never calls the linker. The fact you specified -o a.out overrides the default name of file.o Try the command file a.out And see what the file type of a.out is? ---- -----Original Message----- From: Giorgos Papamarkos [mailto:kaizer_soze_gp@yahoo.gr] Sent: Tuesday, November 16, 2004 1:43 PM To: suse-programming-e(a)suse.com Subject: [suse-programming-e] Cannot run compiled programs from GCC -- SuSE 9.2 Hi there, I just installed SuSE 9.2 but I face a SERIOUS and extremely nasty problem. When I compile a program with GCC/G++ I cannot run it getting instead a: *bash: ./a.out: Permission denied* As you can understand I cannot work with that. Has anyone of you any idea? Don't tell me that this is a matter of permissions, 'cause it is not :) Thanks a lot.
