I am trying to port TBB 2.2 to HP-UX IA64 platform. I happen to encounter an error when I was building TBB 2.2. The error is regarding the undefining of posix_memalign in /src/test/test_malloc/test_malloc_compliance.cpp (line no: 257). I checked for the defination of posix_memalign and everywhere the defination is given as
int posix_memalign (void **__memptr, size_t __alignment, size_t __size)
Line no: 257 in test_malloc_compliance.cpp is
What is the above line supposed to mean (just giving posix_memalign without any parameters)?. Is there any other defination for posix_memalign such that it does not have any parameters?.
Thanks for the reply. When you say that Rposix_memalign is assigned to posix_memalign, should it not be with parameters?. How can you define it just as posix_memalign() when actually its definition is int posix_memalign (void **__memptr, size_t __alignment, size_t __size) . I tried finding the definition of posix_memalign, but could not. The header files that are included are #include #include #include #include #include
I checked in each of these files and I could not find the definition of posix_memalign. Is posix_memalign a standard function (I mean is it defined in /lib or someother system file)?. I was trying to solve other errors in the file build.txt. I encountered on errors such as error #3696-D: cannot open source file "tbb/parallel_for.h"
I am not able to understand how this type of error can happen. The only errors before this error is the posix_memalign and test_malloc_compliance.cpp errors. Could you tell me what is going on here as to why these errors are occuring. I have attached the build output with my previous post
posix_memalign is standard function. man posix_memalign should point out correct header where it declared. If there is no such man on HP-UX, you can tryto find it via something like find /usr/include/ -type f|xargs grep posix_memalign If there is no this function, you can take care of it by adding HP-UX to Solaris and Mac OS X in the line #elif __APPLE__ || __sun // Max OS X and Solaris don't have posix_memalign in setSystemAllocs() function.
Hi Johnson, What solution did you end up with? If you have some changes to the test and/or other codethat are must for HP-UX, please consider contributing those to TBB so that we can incorporate into future versions.
What I mean by saying "It really worked" was that the posix_memalign error was rectified and now I am presently stuck with a linker error: Unsatisfied symbol. I have posted this here. I am trying to port TBB 2.2 to HPUX IA64 platform. As soon as I have ported it, I plan to contribute it here. But since I am an amateur and that this is my university project, it would be great if I can get help whenever I encounter errors. I will contribute whatever I get out of this.
