Hello Jurgen,
I'm assuming that everyone is aware of the solution for this.
Every unicode file name still has ANSI-dos name (aka ShortName).
You could write a function that would return a short name based on
unicode name of a file. And pass the short name to Assign File
function.

hello,
i've been rebuilding svn version of fpc i386-linux.
i'm building RTL using 'make all install INSTALL_PREFIX=mypath'
mypath is located on a Fat32 disk (flash drive).
All compiled unit files (.o, .ppu) are copied fine, expect for
'Syscall.o' and 'UnixUtil.o'.
they are compiled and present
thanks for the reply.
i guess ppl, using linux os, rarely build on case-insensetive
filesystem. Otherwise, they should be aware of such problems.
thanks,
dmitry

hello Developers.
Does anyone have an experience with converting hex-float numbers from
C to Pascal?
i've converted all OpenCL (cl_platfrom.h, cl.h, cl_gl.h) headers
already,except for the following constants:
CL_FLT_MAX 0x1.fep127f
CL_FLT_MIN 0x1.0p-126f
CL_FLT_EPSILON
Anyway. does FPC community need converted OpenCL headers? i'd like to
share them.
Should they be converted to the proper structure first (/src, make,
fpmake)? there're only 2 files anyway.
I still have not found any reasonable way to convet c-hex-float number
to pascal.
i'm not sure if it's nice
thanks for the reply Marco
I'm working in vision, and I'd be very interested in OpenCL headers.
you can download converted headers from here:
http://wnsoft.com/~dima/opencl.zip
original c headers are available here:
http://www.khronos.org/registry/cl/
cl.h and cl_platform.h is united into
