Android App Development include LDAP on MAC OS X
-
I compiled the framework with this script:
#!/bin/bash #adjust export NDK_LOCATION="/Users/user123/Library/Android/sdk" export ANDROID_NDK_HOME="$NDK_LOCATION/ndk-bundle" export CC="arm-linux-androideabi-gcc" export CXX="arm-linux-androideabi-g++" export RANLIB="arm-linux-androideabi-ranlib" export LD="arm-linux-androideabi-ld" export AR="arm-linux-androideabi-ar" export CROSS_COMPILE="arm-linux-androideabi" #define android api export ANDROID_API=16 export CFLAGS="-D__ANDROID_API__=$ANDROID_API" #install toolchain ${ANDROID_NDK_HOME}/build/tools/make-standalone-toolchain.sh --platform=android-${ANDROID_API} --install-dir=${ANDROID_NDK_HOME}/android-toolchain export PATH="$PATH:$ANDROID_NDK_HOME/android-toolchain/bin" export LIB_DIR="`pwd`/lib" export LDAP_OUTPUT_DIR="${LIB_DIR}/compiled/OpenLDAP" #download lib #git clone https://github.com/openldap/openldap.git cd "$LIB_DIR/openldap" ./configure --host=${CROSS_COMPILE} --prefix="${LDAP_OUTPUT_DIR}" --with-yielding_select=yes make depend make && make installAnd tried to add it in my pro file:

/Edit: solved it, I used deprecated functionality of the library that can be enabled over the macro LDAP_DEPRECATED

What errors and where?
This line looks fishy to me:
--host=${CROSS_COMPILE}The host is your host machine (your Mac), so it should rather be something like x86_64, and not the ARM architecture. But maybe LDAP is using some other convention, I don't know.

My error is:
:-1: error: error: cannot find -lldapI think there is mistake in the .pro file:
The Filestructure is:
- *.pro - lib - compiled - OpenLDAP - lib - include - * - other filesin the lib directory are these files:
liblber-2-devel.so.0 libldap.la liblber-2-devel.so.0.0.0 libldap.so liblber.a libldap_r-2-devel.so.0 liblber.la libldap_r-2-devel.so.0.0.0 liblber.so libldap_r.a libldap-2-devel.so.0 libldap_r.la libldap-2-devel.so.0.0.0 libldap_r.so libldap.a -
@mkmp29 said in Android App Development include LDAP on MAC OS X:
-L lib/compiled/OpenLDAP/lib -lldap
There should be no space between '-L' and your library search path.

ANDROID_EXTRA_LIBS += lib/compiled/OpenLDAP/lib/libldap.soDidn't work either. I just get the message for multiple lib function:

Hi,
Did you check the x86 vs x86_64 architecture for your library ?
-
No there's not.
The only alternative is to check whether your targets already have them available in their root filesystem and re-use them.

I can compile the application and push it to the virtual device. But i get the error:
W System.err: Caused by: java.lang.UnsatisfiedLinkError: dlopen failed: library "liblber-2-devel.so.0" not foundThis file is contained in the lib folder of my cross compiled library. I read a little bit and tried to load the library during runtime with the QT Object: QLibrary and the function load. But it didnt work.
this is the part of my .pro file

IIRC, android doesn't support library versioning so ensure that you don't have a symbolic link copied to your package but a copy of the library.

I removed the links from the libraries, deleted the links and renamed the lib to its original name, but the error still appears...
-
Which one ? The missing symbol or the dlopen error ?
-
Why are you dlopening the library on Android rather than linking to it ?

this does the the library...
Can you rephrase that please ? I don't understand what it means at all.

If I get it right, he means that he links the LDAP library. That library, however, uses dlopen internally to access yet another library.
