SGABIOS彙編錯誤

Question

我試圖在我的Macbook Pro上構建SGABIOS。不幸的是，我收到了一些我不熟悉的奇怪的編譯錯誤。當我試圖運行make，這裏是輸出我得到：

Ajax-2:sgabios-read-only dash$ make 
rm -f .depend 
cc -E -M -Wall -Os -m32 -nostdlib sgabios.S >.tmpdepend && mv .tmpdepend .depend 
make clean 
rm -f sgabios.bin csum8 sgabios.o *.elf *.srec *.com version.h 
touch sgabios.S 
cc -Wall -Os -m32 -nostdlib -DBUILD_DATE="\"Fri Aug 31 19:10:03 UTC 2012\"" -DBUILD_SHORT_DATE="\"08/31/12\"" -DBUILD_HOST="\"Ajax-2.local\"" -DBUILD_USER="\"dash\"" -c -o sgabios.o sgabios.S 
sgabios.S:24:Unknown pseudo-op: .type 
sgabios.S:24:Rest of line ignored. 1st junk character valued 95 (_). 
sgabios.S:30:Unknown pseudo-op: .size 
sgabios.S:30:Rest of line ignored. 1st junk character valued 95 (_). 
sgabios.S:33:Unknown pseudo-op: .type 
sgabios.S:33:Rest of line ignored. 1st junk character valued 108 (l). 
sgabios.S:156:Alignment too large: 15. assumed. 
make: *** [sgabios.o] Error 1 

我GCC版本信息如下：

Ajax-2:sgabios-read-only dash$ gcc -v 
Using built-in specs.

我已經做了廣泛的谷歌搜索和胡鬧和似乎沒有任何工作。我也嘗試了cygwin的整個混亂，並且我得到了幾乎相同的東西。供大家參考，我已上載從最新發布的一些文件：

sgabios.S

sgabios.h

Makefile

更新：Cygwin中化妝的發佈輸出：

dash@Ajax_virtual ~/sgabios-read-only

這是因爲彙編程序文件寫成了f或GNU as，但OS X不使用它，而是使用它自己的彙編程序。

此外，根據documentation on the .type directive GNU指令的含義取決於目標平臺。鏈接文件中的指令僅對在Linux（和其他單元）上使用的ELF目標有效，但cygwin是COFF目標。
