[ft] Building FT2 for embedded architectures
Hi, I'd like to build FT2 for the ARM Cortex-M3 architecture to use it for text output on a display. My naive attempt to make it use the available cross-compiler by passing the --host option to ./configure did (of course) not yield a working result; we'll can't blame for for trying ;) I'd like to build FT2 specific to my needs, that are: - static library - no builtin zlib, lzw and bzip2 (some compression library will be linked into the firmware image eventually) - selecting the supported font formats Most of the configuration will probably hand tailored to the target system anyway. So what I look for is some pointers in how to manually configure the FT2 build without the assistance of some autoconf/automake build system.

Here you go:
This file contains any messages produced by compilers while

It was created by FreeType configure 2.4.11, which was
generated by GNU Autoconf 2.69. Invocation command line was

your arm-non-eabi-gcc seems to have a difficulty to
make a binary executable. If you want to make a hello-world
binary executable for the target system, how do you compile
it?

I'm successfully compiling and linking programs using this very compiler. I put the blame on the brain dead automake/autoconf system that tries to execute the generated binary on the compiler system which of course will not work. Preferrably there would be no configure script running at all. I'd really prefer to configure the build myself, specific to my needs. Any automagic is a No-Go in this project anyways. If you want to make a hello-world binary executable for the target system, how do you compile it? Here's the Makefile of the small test program I started with. ### Makefile ### all: arm-none-eabi-gcc -I. -c -fno-common -O0 -g -mcpu=cortex-m3 -mthumb main.c arm-none-eabi-ld -Tstm32.ld -nostartfiles -o main.elf main.o arm-none-eabi-objcopy -Obinary main.elf main.bin flash: main.bin stm32_flash.pl main.bin clean: rm main.o main.elf main.bin ### Makefile (END) ### stm32_flash.pl is a small Perl script talking to OpenOCD, to flash the image via JTAG. Anyway, the linker produces a valid ELF. dw@hilbert: ~/…/stm32f_test file main.elf main.elf: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped Already the project is quite progressed. I have the uC talking to the display, a SD-Card from which it loads images and blits it onto the display, it has a working IP stack talking to an Ethernet PHY and a HTTP server running, that serves static content from the SD-Card as well as dynamically generated pages. So I can assure you, that the toolchain does work, and very well it does. However there is no POSIX API around, but the build configure apparently tries to configure for Unix, which is of course completely pointless in that situation.
