sizeコマンドの仲間たちで見つけたbin2c.cをビルドしてみます。
まず、bin2c.cが単体でビルドできるか確認します。メイクファイル(makefileやmakefile等)の依存ファイルにbin2c.cがあるか確認。もしかしたらメイクのターゲットからコマンド名も分かるかもしれません。

ありました。
この２行がそうですね。

ターゲットbin2cは、依存ファイルがbin2c.cで、実行するコマンドが、#(CC_FOR_BUILD)です。
binutilsディレクトリ内で、ビルドするようです。
binutilsディレクトリへcdして、configureを実行します。
takk@deb9:~/src/binutils-2.28$ cd binutils takk@deb9:~/src/binutils-2.28/binutils$ ./configure 省略 takk@deb9:~/src/binutils-2.28/binutils$ grep -n bin2c.c * ChangeLog-2007:418: * ar.c, arlex.l, arparse.y, arsup.c, arsup.h, bin2c.c, binemul.c, ChangeLog-2007:991: * bin2c.c: New file.

次に、ターゲット、bin2cを指定してmakeします。
takk@deb9:~/src/binutils-2.28/binutils$ make bin2c gcc -o bin2c -I. -I. -I../bfd -I./../bfd -I./../include -DLOCALEDIR="\"/usr/local/share/locale\"" -Dbin_dummy_emulation=bin_vanilla_emulation -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wstack-usage=262144 -I./../zlib ./bin2c.c takk@deb9:~/src/binutils-2.28/binutils$
ビルドできました。
実行ファイルを確認しましょう。
takk@deb9:~/src/binutils-2.28/binutils$ ls -l bin2c -rwxr-xr-x 1 takk takk 9016 8月 24 22:35 bin2c takk@deb9:~/src/binutils-2.28/binutils$
使い方を確認します。
takk@deb9:~/src/binutils-2.28/binutils$ ./bin2c -h Usage: ./bin2c < input_file > output_file Prints bytes from stdin in hex format. takk@deb9:~/src/binutils-2.28/binutils$
使ってみましょう。bin2c自身をダンプしてみました。
takk@deb9:~/src/binutils-2.28/binutils$ ./bin2c < bin2c | head 0x7f,0x45,0x4c,0x46,0x02,0x01,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x03,0x00,0x3e,0x00,0x01,0x00,0x00,0x00,0xa0,0x07,0x00,0x00,0x00,0x00,0x00,0x00, 0x40,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x78,0x1b,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x40,0x00,0x38,0x00,0x09,0x00,0x40,0x00,0x1f,0x00,0x1e,0x00, 0x06,0x00,0x00,0x00,0x05,0x00,0x00,0x00,0x40,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x40,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x40,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0xf8,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0xf8,0x01,0x00,0x00,0x00,0x00,0x00,0x00, 0x08,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x03,0x00,0x00,0x00,0x04,0x00,0x00,0x00, 0x38,0x02,0x00,0x00,0x00,0x00,0x00,0x00,0x38,0x02,0x00,0x00,0x00,0x00,0x00,0x00, 0x38,0x02,0x00,0x00,0x00,0x00,0x00,0x00,0x1c,0x00,0x00,0x00,0x00,0x00,0x00,0x00, takk@deb9:~/src/binutils-2.28/binutils$
