MMD読込ライブラリSabaをビルドするも使えなかった

C++

　ラズパイ4Bで動かず。

情報源

手順

sudo apt-get install libbullet-dev
sudo apt-get install libglfw3-dev

git clone https://github.com/benikabocha/saba.git
cd saba
mkdir build
cd build
cmake ..
make -j4
./saba_viewer

　makeでエラーになった……。

[ 89%] Built target SabaViewer
make: *** [Makefile:95: all] エラー 2

　makeの-j4オプションをとって再実行すると進んだが、やはり同じエラー。

make

　./build/Makefileの95行目は以下。

 $(MAKE) -f CMakeFiles/Makefile2 all

　./build/CMakeFiles/Makefile2

　以下でググると「メモリ不足」が原因らしい。

make: *** [Makefile:95: all] エラー 2

　ログを見るとコードにエラーがあるように見える。

エラー：「GLFW_TRANSPARENT_FRAMEBUFFER」はこのスコープで宣言されていません
注：代替案：「GL_READ_FRAMEBUFFER」

　ググってみると定義値が出た。

#define GLFW_TRANSPARENT_FRAMEBUFFER   0x0002000A

Window framebuffer transparency window hint and window attribute.

vim /tmp/work/saba/example/simple_mmd_viewer_glfw.cpp

　:1245、Enterして1245行目を表示。定義#define ...を追加。:wで書き込み。

#define GLFW_TRANSPARENT_FRAMEBUFFER   0x0002000A
        glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GL_TRUE);

　再びビルド。

　実行するもエラー……。

　さっきコード修正した行を以下のように修正。これはエラーに出ていたGL_READ_FRAMEBUFFERを使ってみた。

//#define GLFW_TRANSPARENT_FRAMEBUFFER   0x0002000A
//     glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GL_TRUE);
        glfwWindowHint(GL_READ_FRAMEBUFFER, GL_TRUE);

　再度実行するも、同様のエラー……。

　GLFWをビルドしてみる。

CMake Deprecation Warning at external/glfw/CMakeLists.txt:10 (cmake_policy):
  The OLD behavior for policy CMP0042 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

　ダメ。わけわからん。

所感

　Sabaは使えなかった。
