perhaps this code by Richard may be of interest to you https://www.freebasic.net/forum/viewtopic.php?p=191571#p191571 I incorporated it in your example #INCLUDE "dir.bi" CHDIR "C:\Users\padawan\FreeBASIC-1.05.0-win64" DECLARE SUB listFiles (filespec AS STRING, attrib AS INTEGER) ...

@counting_pine
I just went by this information here http://lists.llvm.org/pipermail/llvm-bu ... 32475.html
it seems to be a reoccurring bug.

hello St_W what I did was to build just the compiler in macOS High Sierra and the runtime libs in macOS Mojave, this is certainly only a temporary solution until Apple fixes the llvm gcc compiler. presently I am using X11 for the graphics but I don't know how long that will continue, I believe that ...

never mind, it's a bug in Apple's LLVM gcc

trying to compile FB in macOS Mojave gives the following error (the runtime libraries build ok) make FBFLAGS="-asm att" ENABLE_XQUARTZ=1 compiler FBC src/compiler/obj/fb.o src/compiler/obj/fb.c:1362:2: error: indirect goto in function with no address-of-label expressions goto *vr$4; ^ src/...

thank you dodicat, yes Chebyshev series often give near minimax approximations and are relatively easy to calculate.

thank you dodicat for participating :-) I wanted to know whether my latest version of clongdouble would work for you, in some cases, it can be significantly faster than double, though in most cases it's slower. what I found interesting is how efficiently gcc implements the math functions in x64, the...

dodicat, the Chebyshev coefficients of the program I posted are correct, but the polynomial coefficients don't look right, I copied the program ages ago from somewhere, need to figure out what's wrong. on the other hand, your program's Chebyshev coefficients don't look right but the polynomial coeff...

@dodicat would you please test this version and see if you find any anomalies? you will need ioldouble.bi from first post thank you [ I ran the minimax program with x(100000, 15) and 1000 iterations without any problems ] FBwin64, use -asm att #include "ioldouble.bi" type clongdouble as ul...

I reuploaded the corrected code and included both 32 and 64-bit libs :-)

my apologies, here's the corrected FB code, this should work in both 32 and 64-bit #inclib "cldbl" type ext #ifdef __FB_WIN32__ #ifdef __FB_64BIT__ #define numberoflongs 4 #else #define numberoflongs 3 #endif #endif as ulong ext_longs(1 to numberoflongs) Declare constructor () Declare dest...

did you build the library from the sources?
there's one thing I forgot, the ext type should be 12-bytes in 32-bit mode and 16-bytes in 64-bit, need to fix that.
if you are running in 32-bit, then perhaps changing the ext type to be 12-bytes will fix the problem.
anyway, thanks for testing.

got tired chasing after bugs, so I made a Wrapper for long double math in C, source code only, easy to build.
