Crash with NEF file in scale_colors

Submitted by william on

Hi,
I'm trying out Libraw 14.6 and many images seem to work fine, but an old Nikon D70 NEF is causing crashes that seem to occur in scale_colors.

Can someone please test this file with the latest version and let me know if the crash is real or I am doing something wrong when using the library?

Cannot do "Native Building" using LibRaw-0.15.0-Alpha1

Submitted by Novfrank on

I could build the .lib, .dll and samples using LibRaw-0.14.7 by following the instructions of "Windows: Native Building". However when I tried to do the same thing using LibRaw-0.15.0-Alpha1, I got an error saying that

"cl.exe /EHsc /MP /MT /I. /DWIN32 /O2 /W0 /nologo /DUSE_JPEG /I..\jpeg-8d /DLIBRAW_BUILDLIB /Fo"object\\dcraw_common.obj" /c internal\dcraw_common.cpp
dcraw_common.cpp
.\internal/defines.h(58) : fatal error C1083: Cannot open include file: 'jpeglib.h': No such file or directory"

Does anyone know why??

Build LibRaw for Windows 64bit

Submitted by Anonymous (not verified) on

Hi Everyone,
I've just downloaded LibRaw and I want to use it in my project. I got the source files and I built it in my Visual Studio 2010 as 64 bit. However, When I tried to integrate it to my project, I got the errors below. I believe there is something about the way it is compiled - my project usually only accepts static libs, that might be the problem.
Could you help me? Maybe telling me how to compile LibRaw as static lib...

Error	286	error LNK2005: atoi already defined in MSVCRTD.lib(MSVCR100D.dll)	C:\Pluribus\svn\source\Trunk\build64\Server\src\LIBCMT.lib(atox.obj)

Noob Compilation question on linux (ubuntu 11.10)

Submitted by orangenuke on

Hi,
So I configured and ran make in the libraw folder. The library has been installed.
I just want to compile a very simple program on this page http://www.libraw.org/docs/Samples-LibRaw-eng.html
I have replaced the function name with main and file pointer with a constant.
What I don't get is to how to actually compile it.

I run the following command in the terminal
g++ -o rawexec -I/usr/local/include -L/usr/local/lib -lraw librawfile.cpp
and get a bunch of errors:
/usr/local/lib/libraw.so: undefined reference to `GOMP_loop_dynamic_next'

Getting OpenMP to compile on OS X

Submitted by celstark on

I've had issues getting OpenMP going on the Mac, both on a 10.6 / XCode3 system and on a 10.7 / XCode 4 system. The configure script says it's not available, but it is. FWIW, I can work around this by changing the configure script's sample OpenMP code (line 15359) to:

/* Override any GCC internal prototype to avoid an error.
Use char because int might match the return type of a GCC
builtin and then its argument prototype would still apply. */
#ifdef __cplusplus
extern "C"
#endif
#include "omp.h"
int
main ()
{
omp_set_num_threads (2);
int count;

CrossCompiling for Android

Submitted by peterdk on

I am trying to compile LibRaw for android, but I am getting stuck.

I downloaded the ndk, setup a standalone toolchain for android-9, added that bin folder as first to my path,
and ran ./configure --host=arm-linux-androideabi

I did need to update the config.sub file since it was very old and did not recognize this host setting. After that it completely ran ./configure and I tried to run make.

Here it however failed fast: 

LibRaw-0.14.4$ make
depbase=`echo internal/dcraw_common.lo | sed 's|[^/]*$|.deps/&|;s|\.lo$||'`;\
