Hello everyone! I was trying to compile fdlibm for prizmSDK 0.3, but he won't compile, nor even init the compilation:
Code: k_standard.c:16:19: fatal error: errno.h: No such file or directory
compilation terminated.
make: *** [k_standard.o] Error 1
Why won't it compile? errno.h is not in the include folder, and trying to compile with the most release of libfxcg here gives the same error...
WHat should i do?
Well, try creating your own errno.h since there's no actual code, they're just defines. You could also use one published somewhere on the internet or use local copies from /usr/include/{*,.}/errno*.h
The file
exists in the canonical include directory, so there's something misconfigured in your build environment.
I'm not ionly including the header, I tried replacing the libraires too!
I'm using too the Prizsdk just like It given in the PRizm Wiki... With only prizm-ld edited to incrase ram to 500k and another batch in my projects to copy the g3a directly on my prizm...
EDIT/ now, I've fixed the Makefile, and Libm.a is compiled, buyt when using it (-lm to add it Makefile, right?), THere is an error about libm.a
Code: H:/Dev/Casio/PrizmSDK-0.3/lib\libm.a: could not read symbols: File format not re
cognized
collect2: ld returned 1 exit status
make[1]: *** [H:/Dev/Casio/PrizmSDK-0.3/projects/trixel/trixel.bin] Error 1
make: *** [build] Error 2
My point was that the include file exists, so there's something wrong with your include paths (or mysteriously missing files). Paste your Makefile for me, and ensure you have errno.h in sdk/include.
I tried to fix the Makefile, got another copy of PrizmSDK, and it won't again find errno, even with putting the SDK's path in %PATH%
Here's the Makefile:

# There are two options in making libm at fdlibm compile time:
# _IEEE_LIBM --- IEEE libm; smaller, and somewhat faster
# _MULTI_LIBM --- Support multi-standard at runtime by
# imposing wrapper functions defined in
# fdlibm.h:
# _IEEE_MODE -- IEEE
# _XOPEN_MODE -- X/OPEN
# _POSIX_MODE -- POSIX/ANSI
# _SVID3_MODE -- SVID
#
# Here is how to set up CFLAGS to create the desired libm at
# compile time:
#
# CFLAGS = -D_IEEE_LIBM ... IEEE libm (recommended)
# CFLAGS = -D_SVID3_MODE ... Multi-standard supported
# libm with SVID as the
# default standard
# CFLAGS = -D_XOPEN_MODE ... Multi-standard supported
# libm with XOPEN as the
# default standard
# CFLAGS = -D_POSIX_MODE ... Multi-standard supported
# libm with POSIX as the
# default standard
# CFLAGS = ... Multi-standard supported
# libm with IEEE as the
# default standard
#
# NOTE: if scalb's second arguement is an int, then one must
# define _SCALB_INT in CFLAGS. The default prototype of scalb
# is double scalb(double, double)
#
#
# Default IEEE libm
#
CFLAGS = -D_IEEE_LIBM

all: libm.a
libm.a : $(obj)
sh3eb-elf-ar cru libm.a $(obj)
sh3eb-elf-ranlib libm.a
source: $(src) README
clean:
rm *.o
rm *.a
And the lib : http://dl.dropbox.com/u/23313407/AUTRES/libm.a compiled with CC flag : GCC, because sh3eb-elf-gcc won't work, ging the "errno" error
They way you're going about this makes it hard to help, because you seem to be trying things randomly until something happens, and based on your comments on SAX, you got it to compile before with some other compiler.
From unpacking your archive, that is indeed the case:
Code: $ ar x libm.a
$ file s_tanh.o
s_tanh.o: 80386 COFF executable not stripped - version 30821
Whereas it should look like those provided by libc:Code: $ ar x libc.a
$ file stdlib.o
stdlib.o: ELF 32-bit MSB relocatable, Renesas SH, version 1 (SYSV), not stripped
So of course that didn't work, you built it for the wrong system.
I suspect your sh3 compiler is confused about where to look for include files (which seems unusual in any case, since we're actually dumping things in the compiler's global include directory, if I correctly understand how it's configured). Try explicitly specifying the include path in your CLAGS. Something like -Ipath/to/include.
Another erros! :p
Code: H:/Dev/Casio/PrizmSDK-0.3/lib\libm.a(e_sqrt.o): In function `___ieee754_sqrt':
e_sqrt.c:(.text+0x598): undefined reference to `___gedf2'
H:/Dev/Casio/PrizmSDK-0.3/lib\libm.a(k_rem_pio2.o): In function `___kernel_rem_p
io2':
k_rem_pio2.c:(.text+0x630): undefined reference to `___gedf2'
k_rem_pio2.c:(.text+0xbf4): undefined reference to `___gedf2'

Since the old distribution CFLAGS are probably overzealous at this point, I think you need to explicitly link against libgcc. The required symbol (which is a floating-point >= check) is indeed exported by libgcc:
Code: $ nm -s /var/lib/gcc/sh3eb-elf/4.7.2/libgcc.a | grep ___gedf2
___gedf2 in _ge_df.o
U ___gedf2
00000000 T ___gedf2
So -lgcc should help with that, assuming the old Windows binaries have the same features as my build.
In my project, lgcc is already present, unless you mean put lgcc in the fdlibm's Makefile.
