Compiling Qt for Native client.

Qt for Google Native Client supports building on either Mac or Linux systems. The resulting

binaries run on any NaCl-enabled x86 system.

After installing Native Client (and testing the installation following the instructions), 

make sure the gcc binaries and sel_ldr are in your path. For example:

Mac:

export PATH=$PATH:/path/to/ncal/build/native_client/src/third_party/nacl_sdk/mac/sdk/nacl-sdk/bin

export PATH=$PATH:/path/to/ncal/build/native_client/scons-out/opt-mac-x86-32/staging/

Linux:

export PATH=$PATH:/path/to/ncal/build/native_client/src/third_party/nacl_sdk/linux/sdk/nacl-sdk/bin/

export PATH=$PATH:/path/to/ncal/build/native_client/scons-out/opt-linux-x86-32/staging/

(Test by running nacl-gcc and sel_ldr, which should be in the path now)

Configure Qt

./configure -nacl /path/to/nacl/build

(If you get a "The target system byte order could not be detected" error message,

then nacl-gcc isn`t in your path.)

Build Qt

cd src/tools; make ; cd ../.. (workaround to build moc etc. NOTE: edit the linker

                               line and remove "-L"library paths poiting to the native

			       client installation if you get linker errors.)

make sub-src (should succeed)

make -k (will build as many examples and demos as possible, and then fail)

Test (sel_ldr)

Run: sel_ldr examples/widgets/wiggly/wiggly

Test (browser)

Use tools/nacldemoserver to browse the examples. Nacldemoserver needs to be compiled

for the host system - use a different Qt buld, not the NaCl one:

cd tools/nacldemoserver

/path/to/other/qmake -nocache

make

./nacldemoserver
