Static and dynamic library linking

由 纵然是瞬间 提交于 2019-12-11 01:46:17
问题 In C++, static library A is linked into dynamic libraries B and C. If a class, Foo, is used in A which is defined in B, will C link if it doesn't use Foo? I thought the answer was yes, but I am now running into a problem with xlc_r7 where library C says Foo is an undefined symbol, which it is as far as C is concerned. My problem with that is Library C isn't using the class referencing it. This links in Win32 (VC6) and OpenVMS. Is this a linker discrepancy or a PBCAK? New info: B depends on C,

Equivalent of fesetflushtozero() on various Unices

由 最后都变了- 提交于 2019-12-11 01:31:18
问题 This question was migrated from Unix & Linux Stack Exchange because it can be answered on Stack Overflow. Migrated 6 years ago . HP-UX's libc has the function fesetflushtozero to switch floating-point behavior between “gradual underflow” and “flush to zero”. Despite combing through documentation and man pages of several Unix libc's (including glibc), I have yet to find how to achieve the same thing in other Unices. I'm particularly interest in Linux/glibc, Solaris and AIX. 回答1: As you have

AIX equivalent for 'date --date'

由 不问归期 提交于 2019-12-10 22:49:31
问题 I frequently use the date command with the --date option on linux servers like date --date="3min" However the -d/--date option don't seems available on AIX server : https://www.ibm.com/support/knowledgecenter/ssw_aix_61/com.ibm.aix.cmds2/date.htm Is it possible, and how can we get the same result as the following command: date --utc --date "now $TIMEDELTA" +"%Y%m%d-%H")` in an AIX environment ? I don't have, and can't have, any root access to the server. 回答1: A few options come to mind:

AIX process memory is increasing with malloc free calls in loop

由 烂漫一生 提交于 2019-12-10 17:46:35
问题 I am running this code on AIX 6.1 while(true) { int a = rand(); //generate a random integer value void* test = malloc(a*a); //allocate large chunk of memory block usleep(3000000); //sleep for 3 sec free(test); // release memory block } using MALLOCTYPE=buckets My observation is Resident set size(real memory) and data section size for process is continuously increasing. This is check by command ps v PID pg sp value shown in topas for process is slowly increasing. Can someone justify this

compiling numpy for python3 for AIX works but import fails

由 ℡╲_俬逩灬. 提交于 2019-12-10 16:55:35
问题 Has someone had success building the numpy package for AIX6.1 or 7.1? I downloaded numpy-1.9.2.tar.gz and ran "python3 setup.py install". After patching a few source files it compiles. However, when I try to import numpy it says: ImportError: 0509-022 Cannot load module /python3.4/site-packages/numpy/core/multiarray.so. 0509-187 The local-exec model was used for thread-local storage, but the module is not the main program. 0509-193 Examine the .loader section header with the 'dump -Hv'

SWIG crashes on AIX (with python, and probably everything else SWIG support)

由 痞子三分冷 提交于 2019-12-09 21:57:06
问题 SWIG compiles and install easily on AIX. Unfortunately, a simple SWIG hello world (which also compiles - but not so easily) crashes with Segmentation Fault or Illegal Instruction (depending on some details of the compilation/linker process). This happens with both gcc and xlc (IBM c compiler). I tried only the native AIX linker ld, because the homonyms GNU ld was not installed on my system. File: example.c #include <time.h> double My_variable = 3.0; int fact(int n) { if (n <= 1) return 1;
