Cross compiling
To build toolchain for raspberry pi, go here: http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi/
Make sure to enable C++ (his instructions omit that part).
This may be handy for ARM work: https://www.baeldung.com/linux/arm64-armel-armhf-overview
Generic (works on most source packages)
CC=arm-unknown-linux-gnueabi-gcc ./configure --prefix={pathtoyourxtools}/x-tools/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi --host=arm
make
make install
mpolib
CC=arm-unknown-linux-gnueabi-gcc ./configure CPPFLAGS=-I/home/matt/x-tools/arm-unknown-linux-gnueabi/include LDFLAGS=-L/home/matt/x-tools/arm-unknown-linux-gnueabi/lib --prefix=/home/matt/x-tools/arm-unknown-linux-gnueabi --host=arm
Zlib v1.2.7
The configure command is:
CHOST=arm-unknown-linux-gnueabi ./configure --prefix={sameasgeneric}
(ignore the error you get at the end)
then
make make install
expat v2.1.0
generic
jansson
generic
OpenSSL v1.0.1c
export cross=arm-unknown-linux-gnueabi-
./Configure dist threads -D_REENTRANT --prefix={same as generic}
make CC="${cross}gcc" AR="${cross}ar r" RANLIB="${cross}ranlib"
For mingw32 (running on linux, building win32 binaries)
Read the INSTALL.W32 file and search for "cross-compile" in those instructions.
libogg v1.2.0
generic
libusb v0.1.12/v1.0.9
Same as generic except "--host=arm-unknown-linux-gnueabi"
NOTE: libFTDI is built against the v0.1 API, not the v1.0 API.
libvorbis v1.3.1
generic
gmock v1.5.0
CC=arm-unknown-linux-gnueabi-gcc CXX=arm-unknown-linux-gnueabi-g++ ./configure --prefix={sameasgeneric} --host=arm
wxWidgets (on linux, targetting win32)
./configure --prefix={whatever} --host=i686-w64-mingw32 --build=i686-linux --your_optional_switches
