Hey guys, I'm once again having problems with the code in alpm. I can't seem to find out how to correctly register databases. I've the bindings basically ready, and need to do the implementation now (pyalpm). So, the following problem occured: I set the database path to /var/lib/pacman (or /var/lib/pacman/community, tried both). It seems as if alpm_option_set_dbpath can't cause errors (void return), so i ignored it. alpm_trans_init runs without returning -1, so i expect it to be succeeded. On alpm_trans_addtarget, i finally get the -1, with pm_errno 11, meaning PM_ERR_DB_NULL. I don't know (lacking docs) what this means, and why this can occur. Do you have any hints for me? Some codelines: cdef pyalpm_config c_config c_config = pyalpm_config() config = c_config alpm_initialize() def addPackage(in_pname) db = config.getDatabasePath() print db # output is OK pyalpm_db_register('community') if (alpm_trans_init(PM_TRANS_TYPE_ADD, <pmtransflag_t((<int>PM_TRANS_FLAG_CASCADE) | (<int>PM_TRANS_FLAG_RECURSE)), NULL, NULL, NULL) == -1): os.remove("/tmp/pacman.lck") print pm_errno return -1 if (alpm_trans_addtarget(in_name) == -1): os.remove("/tmp/pacman.lck") print pm_errno return -2 # here it exits ###test.py### import pyalpm pyalpm.config.setDatabasePath('/var/lib/pacman') print pyalpm.addPackage('yaz') ###output### 11 -2 Seems as if i'm missing something -- Yours, Georg (STiAT)
