Toolchain + Directfb: JPEG support is missing

[FrEEzEr]

Hello NMT programmers

I really want to start programming for the NMT using C and directfb, but I just can't get past the process of installing the toolchain and compiling directfb apps (properly because of my inexperience with unix).

What did I do to make it running:

1. Installed Ubuntu
2. Downloaded the toolchain from lundman (linux version)
3. Installed the jpeglib-dev and freetype2-dev package
4. Followed these steps: http://lundman.net/wiki/index.php/NMT:directfb
5. Tried the same steps but instead of Ubuntu I used Suse
   

I just keep getting the error "JPEG support is missing - many applications won't work correctly!".

Apparently when I do "./configure --target=mipsel-linux-uclibc --host=mipsel-linux-uclibc --enable-x11=no --enable-png=no --with-gfxdrivers=none --build=i386 " it can't find the JPEG library, but it IS installed!

In this thread someone had the same problem and he knows how to fix it. Sadly he didn't respond to my Private Message.

Anyone here willing to help me?

Thank you!

OK, first off, keep in mind that I don't know what I'm talking about because I haven't tried this at all. Though I have done some cross-compilation work before.

It sounds to me like you're saying you installed the jpeg and freetype packages from Ubuntu. If so, I think that's your problem. It sets up development packages for the toolchain for you *computer* only. You need to download the source for those packages and manually set them up for your Sigma toolchain.

Curien, you are right. FrEEzEr you have to get the DEV versions of each lib package and compile these with your NMT toolchain to get the libs needed.

I guess you will not bee the first to compile these libs. Maybe we should find a common place to store all NMT libs?

Perhaps Ger Teunis' Community Software Installer?
Why not have a dev section with libraries, dev tools and utilities?

Thank you all for your input!

I tried compiling libjpeg for the toolchain but I'm getting nowhere

What I have done:

• Downloaded the libjpeg source package
• sudo ./configure --target=mipsel-linux-uclibc --host=mipsel-linux-uclibc --build=i386
• make
• make install
• Tried running DirectFB ./configure and still the same error
  

• sudo ./configure --target=mipsel-linux-uclibc --prefix=/usr/local/mips/mipsel-linux-uclibc --host=mipsel-linux-uclibc --build=i386
• make
• make install
• Tried running DirectFB ./configure again and still the same error
  

So I thought maybe the compiling of the JPEG went ok but I need to point DirectFB to the right lib folder so I tried these commands:

• ./configure --target=mipsel-linux-uclibc --host=mipsel-linux-uclibc --enable-x11=no --enable-png=no --with-gfxdrivers=none --build=i386 --bindir=/usr/local/mips/mipsel-linux-uclibc/bin/
• ./configure --target=mipsel-linux-uclibc --host=mipsel-linux-uclibc --enable-x11=no --enable-png=no --with-gfxdrivers=none --build=i386 --libdir=/usr/local/lib
• ./configure --target=mipsel-linux-uclibc --host=mipsel-linux-uclibc --enable-x11=no --enable-png=no --with-gfxdrivers=none --build=i386 --libdir=/usr/local/mips/lib
  

All with the same outcome.... "JPEG support is missing - many applications won't work correctly!"

Can someone please explain to me how to do it?

[FrEEzEr]

Finally I figures it out!

Steps I did to make it working:

• Download libjpeg sources, extract and go to dir in terminal
• sudo ./configure --target=mipsel-linux-uclibc --prefix=/usr/local/mips/mipsel-linux-uclibc --host=mipsel-linux-uclibc --build=i386
• sudo mkdir /usr/local/mips/mipsel-linux-uclibc/include
• sudo make
• sudo make install-lib
  

Now I can finally start coding some NMT apps

Great you finally got it working!
