should other compilers besides gcc work (i.e. icc or pgcc)?

[Former user]

If I set CC=icc, run ./configure; make a slew of errors like this:

SHT.c(485): error: expected an expression for (int it=typ_start; it<SHT_NTYP; it++) {

and this

SHT.c(2541): warning #188: enumerated type mixed with another type shtns_set_grid(sht_data, type | layout, eps, nlat, *nphi);

Looks like icc doesn't support these constructs. Same thing happens with the portland group c compiler. Is this a bug, or gcc the only compiler you intend to support?

[Nathanaël Schaeffer]

I hoped this would be supported by any compiler, but I admit I only tested with gcc :) I will look into it, but if you have time to do so, could you append "(int)" before "typ_start" and "SHT_NTYP" ? I suspect it could solve the problem. (Note that the agressive vectorization should only work with gcc, resulting in faster code.)

[Nathanaël Schaeffer]

I just tested with icc 9.1 and icc 12.1.4. Without changing anything, SHTns 2.2.4 compiles just fine, although a lot of warnings are issued. What version of icc are you using ?

Concerning pgcc, I have no access to this compiler, but if you send me the errors, I will fix them.

[Former user]

You are right - it works with icc as long as you compile with -std=gnu99. I must have modified the Makefile to remove that compiler flag while removing some of the other gcc flags that icc didn't understand. I will try again with pgcc and let you know.

[Former user]

pgcc doesn't understand -pipe. After removing that from the Makefile, I get

Could you try again using ./configure --disable-simd ? It looks like pgcc pretends to be gcc, but it isn't.

[Nathanaël Schaeffer]

SHTns supports three compilers: gcc, icc and clang
