As it turns out, I must use the Solaris Studio compiler to take advantage of OpenMP on Solaris. This compiler is much more picky in terms of not allowing certain non-standard constructs.
Here are the problems I've had: *Enum values must be a long or unsigned long* In SystemLimits.hh, LARGE_INT and SMALL_INT are declared as type long long (with the LL suffix). This is actually not allowed. I would like to suggest using a namespace and constant variables instead. (if this is done in other cases as well, this would get rid of all the warnings the compiler emits when assigning a value to an enum that has not been previously declared). *Zero-size arrays are not allowed* In CDR_string.hh, the *dim* member is declared of size 0. This is allowed by GCC as an extension, but is non-standard. There is an flag that enables this extension in the Solaris compiler too, but it may be a good idea to remove this altogether if possible. If not, the Solaris Studio flag that is needed is: *-features=zla* The same thing happens in ValueHistory.cc when value history is disabled (since VALUEHISTORY_SIZE becomes 0). *C++ does not support non-constant array sizes* Declaring an array with a size computed at runtime is not actually allowed (it's supported in modern C, and also supported in C++ as an extension). The solution is to use alloca() instead. I.e, change the following: int foo[bar]; to: int *foo = (int *)alloca(sizeof(int) * bar); This happens at: - APmain.cc:290 - AP210.cc:151 and 192 - Archive.cc:318 - LibPaths.cc:74 and 81 - PrimitiveFunction.cc:2285, 2329 and 2940 - QuadFunction.cc:1465 - Quad_SVx.cc:268 - SkalarFunction.cc:505 - Symbol.cc:205 and 764 - SystemVariable.cc:553 *The option -g2 is illegal, in src/APs/Makefile* I'm not sure what this option does even in GCC, but Solaris Studio does not accept it. *Overloading ambiguity for maths functions* The following errors are fixed by casting the inner argument to double: "IntCell.cc", line 222: Error: Overloading ambiguity between "std::exp(double)" and "std::exp(float)". "IntCell.cc", line 234: Error: Overloading ambiguity between "std::log(double)" and "std::log(float)". "IntCell.cc", line 234: Error: Overloading ambiguity between "std::log(double)" and "std::log(float)". "IntCell.cc", line 230: Error: Overloading ambiguity between "std::log(double)" and "std::log(float)". "IntCell.cc", line 234: Error: Overloading ambiguity between "std::log(double)" and "std::log(float)". *The include file <locale.h> needs to be included to access the LC_ symbols* This file needs to be included from SystemVariable.cc *munmap() does not follow POSIX* By default, Solaris expects the first argument to munmap() to be a char *as opposed to void *. This is non-standard, but standard behaviour can be achieved by setting the #define _XPG4_2 However... Doing this causes some other issues so it might just be best to #ifdef that thing and cast the argument to char * on Solaris. Regards, Elias
