* 結論 [#k9e7df7b]
どうやらこういう風に使うものじゃなさそう、
ということがようやくわかってきました。
以下の内容にはあまり意味が無いことになってしまいました。
* libmetal [#ad27d94c]
https://github.com/OpenAMP/libmetal
linux, freertos, baremetal で共通に使えるライブラリ API を提供し、
デバイスへのアクセスや割り込み制御、メモリ確保、その他ユーティリティ機能を提供するもの
のようです。
- Linux user space (based on UIO and VFIO support in the kernel)
- RTOS (with and without virtual memory)
- Bare-metal environments
となっているので、metal_xxx という共通の名前の関数ではあるものの、
環境によって実装を変え、適切な API 呼び出しに変換してくれる、ということみたい。
** petalinux ではチェックボックス一つでインストール可能？ [#w1978a46]
petalinux-config -c rootfs で選択できるので、
これでインストールできルっぽい？
ただこれでやるとユーザープロジェクトもすべて petalinux
のビルドシステムを使わなければならなくなってややこしい。
GitHub で公開されているソースから単独でインストールできないものか、
と四苦八苦しているのがこのページです。
** libhugetlbfs-dev が必要 [#kb5f67e2]
make には cmake, doxygen, libsysfs-dev, libhugetlbfs-dev が必要になりますが、
Debian stretch には libhugetlbfs-dev が含まれていませんでした。Ubuntu には含まれていました。
** cmake では out-of-source build が推奨されているそうで [#c65d31dc]
http://stackoverflow.com/questions/27247123/how-to-clean-up-the-project-files-generated-by-cmake ~
cmake は out-of-source build が推奨されているそうで・・・最初、これがわからず苦労しました。

Target が Linux/x86_64 になってしまっている？
** zynq7 用の設定を読み込む [#ofb6845b]
Target を arm にするにはどうするのか、
LANG:console
$ cd ~/z-turn/libmetal
$ grep -s CROSS `find`
./build/CMakeFiles/3.5.1/CMakeSystem.cmake:set(CMAKE_CROSSCOMPILING "FALSE")

./cmake/platforms/cross-generic-gcc.cmake:CMAKE_FORCE_CXX_COMPILER ("${CROSS_PREFIX}g++" GNU)
$ arm-^T
...
arm-linux-gnueabihf-gcc
...
arm-none-eabi-gcc
...
$ cat cmake/platforms/zynq7-generic.cmake
set (CMAKE_SYSTEM_PROCESSOR "arm" CACHE STRING "")
set (MACHINE "zynq7" CACHE STRING "")
set (CROSS_PREFIX "arm-none-eabi-" CACHE STRING "")
set (CMAKE_C_FLAGS "-mcpu=cortex-a9 -mfpu=vfpv3 -mfloat-abi=hard -O2 -g" CACHE STRING "")

CMAKE_FORCE_CXX_COMPILER ("${CROSS_PREFIX}g++" GNU)

$
なので、
- platforms/zynq7-freertos.cmake
- platforms/zynq7-linux.cmake
- platforms/zynq7-generic.cmake
のいずれかが読み込まれてくれると良さそうなのだけれど、、、
実は zynq7-linux だと CROSS_PREFIX が arm-linux-gnueabihf- となってほしいところ、
arm-xilinx-linux-gnueabi- となってしまう？
とにかくこの platforms/*.cmake を読み込ませてみよう、
となったのですが、指定するための正規の方法がわかりませんでした。
** むりやり platform を指定してみる （zynq7-linux 編） [#p73ed525]
そこで、CMakeLists.txt に
LANG:cmake
cmake_minimum_required (VERSION 2.6)
list (APPEND CMAKE_MODULE_PATH
"${CMAKE_SOURCE_DIR}/cmake"
"${CMAKE_SOURCE_DIR}/cmake/modules"
"${CMAKE_SOURCE_DIR}/cmake/platforms")
project (metal C)
+ include (${PLATFORM_NAME})
+
include (CheckIncludeFiles)
include (CheckCSourceCompiles)
include (collect)
include (options)
include (depends)
...
のようにして PLATFORM_NAME へ platform 名を渡せるようにしてみたところ、
LANG:console
$ cd ~/z-turn/libmetal
$ mkdir build_zynq7-linux
$ cd build_zynq7-linux
$ cmake -DPLATFORM_NAME=zynq7-linux ..

project の後に platform 指定を読んだのでは遅いということか。

armhf 向けのものが無いということ。

本当にそうだった。
で、cmake は通ったけれど、今度はインクルードファイルが見つからないと言っている。
/usr/include/sysfs/libsysfs.h は存在しているので、インクルードパスが正しく設定されていないことになる。~
何のための cmake ?
CMAKE_INCLUDE_PATH というのも違うらしいし、include_directories も違うらしい。
で、直接 CMAKE_C_FLAGS を指定すると
LANG:console

のように、少し進んだ。
今度は error: '__regparm__' attribute directive ignored で止まった。
https://gcc.gnu.org/onlinedocs/gcc/x86-Function-Attributes.html
などによると、regparm は gcc の x86 向けのディレクティブで、
関数の引数をレジスタにセットして渡すためのものらしい。
armhf 向けの gcc ではこのディレクティブを無視するぞ、という警告が出て、-Werror
のために警告が即エラーになっている。
/usr/include/pthread.h が x86_64 向けのもので、armhf 向けのもので無いのが問題。
これ、根が深い感じがする。。。

うわ、何されたか全然わからない。
いろいろ調べてみたけれど、 install_manifest.txt という空のファイルができただけな気がする？
lib や inclide/metal にはちゃんと libmetal.so やらインクルードファイルやらができているので、
make install すればこれらが /usr/local/lib やらにコピーされて一件落着、となるはず。
