armv7 embedded device with no Graphical interface

[jasonnnn]

thank you caught that,

now i am getting this one

./configure -xplatform wasm-emscripten -nomake examples -prefix $PWD/qtbase + cd qtbase

Is the compiler findable in your PATH environment variable ?

[jasonnnn]

@sgaist how could I check that ? , i did execute source ./emsdk_env.sh

[SGaist]

First thing, try to call em++ in the same terminal you are currently building Qt in.

@sgaist thanks for supporting, we are finding problems building Emscripten , thatis the main reason why QT will no build. Unfortunately, we may have to give up on QT for this project.

I don't believe you guys would be supporting un on the emscripten side, but just in case here is the build error (next post)

[SGaist]

I'm not sure I understood your issue with the emc compiler.

In any case, the error log is missing.

SOrry for the missing pieces, so I am not sure if i am missing dependencies on my embbeded device, so too prrof concept I am trying to build on an Unbuntu 64, and the problem appears to be the same ,

1 i built emsdk

2 git clone QT5, Qtbase and QTdeclaratives

3 tried to build QT with ./configure -xplatform wasm-emscripten -nomake examples -prefix $PWD/qtbase
then got (execute the call on em++ which appears to be there)

Info: creating super cache file /opt/qt5/.qmake.super
Info: creating cache file /opt/qt5/.qmake.cache

thanks in advance

You seem to use a version of the emsdk that is not mentioned in the Qt for Web Assembly wiki entry.

Did you try to use one of these ?
