Hello everyone,

I am trying to compile Swift in Ubuntu 14.04 and I found several problems. I 
have been trying to compile Swift for some days using my own compiled libraries 
(such us libedit, python, libxml, uuid, sqlite3, libicu, libncurses, etc.) and 
I unable to link them properly.


When I install the libraries mentioned before from the system (using apt-get 
install XXX) I can perfectly compile Swift using the "build-script" with the 
following options:


./swift/utils/build-script --assertions --no-swift-stdlib-assertions --llbuild 
--swiftpm --xctest --lldb --release --foundation -- --install-swift 
--install-lldb --install-llbuild --install-swiftpm --install-xctest 
'--swift-install-components=autolink-driver;compiler;clang-builtin-headers;stdlib;swift-remote-mirror;sdk-overlay;license'
 --build-swift-static-stdlib --build-swift-stdlib-unittest-extra 
--install-destdir=/home/juan 
--installable-package=/home/juan/swift-compiled.tar.gz --install-foundation 
--reconfigure

However, I want to use my own compiled libraries. I have successfully compiled 
all the dependences mentioned before under /home/juan/common, so I have all the 
libraries under /home/juan/common/lib, the binaries under /home/juan/common/bin 
and the headers under /home/juan/common/include. (NOTE: I did install clang, 
ninja-build and cmake using "apt-get install XXX, I just compiled the 
libraries, not the compiling tools).


The problem is that I am unable to configure the "build-script" to use my 
libraries instead of the system ones, so cmake and clang are unable to find and 
link them and the compilation process fails. I have tried to use several 
options but I am still unable to get it. Here you have some of the flags I 
tried:


--extra-cmake-options='-DICU_UC_INCLUDE_DIR=/home/juan/common/include, 
-DICU_UC_LIBRARIES=/home/juancommon/lib, 
-DICU_I18N_INCLUDE_DIR=/home/juan/common/include/, 
-DICU_I18N_LIBRARIES=/home/juan/common/lib, 
-DPYTHON_LIBRARY=/home/juan/python/lib/libpython2.7.so, 
-DPYTHON_INCLUDE_DIR=/home/juan/python/include/python2.7, 
-DCMAKE_CXX_FLAGS=-I/home/juan/common/include, 
-DLIBXML2_INCLUDE_DIR=/home/juancommon/include/libxml2, 
-DLIBXML2_LIBRARIES=/home/juan/common/lib/libxml2.so, 
-DUUID_INCLUDE_DIR=/home/juan/common/include, 
-DUUID_LIBRARY=/home/juan/common/lib/libuuid.so, 
-DCMAKE_EXE_LINKER_FLAGS=-L/home/juan/common/lib’

Does anyone how I can configure the "build-script" properly? I am desperate [😞] 
.


I would appreciate any kind of help very much [😊] .

Best regards,

Juan
