Assembly on linux using as
November 26, 2005 01:47 AM
Hi,
I am trying to learn assembly using GAS syntax. However I get a bunch of errors on doing as -o file.o file.S
This is the source program
I get the following on errors on trying to build the object file
as: "hello.S", line 1: error: invalid character (0x73)
as: "hello.S", line 1: error: statement syntax
as: "hello.S", line 14: error: unknown "%"-symbol
as: "hello.S", line 14: error: statement syntax
as: "hello.S", line 15: error: unknown "%"-symbol
as: "hello.S", line 15: error: statement syntax
as: "hello.S", line 16: error: unknown "%"-symbol
as: "hello.S", line 16: error: statement syntax
as: "hello.S", line 17: error: unknown "%"-symbol
as: "hello.S", line 17: error: statement syntax
as: "hello.S", line 18: error: unknown opcode "int"
as: "hello.S", line 18: error: statement syntax
as: "hello.S", line 21: error: unknown "%"-symbol
as: "hello.S", line 21: error: statement syntax
as: "hello.S", line 22: error: unknown "%"-symbol
as: "hello.S", line 22: error: statement syntax
as: "hello.S", line 23: error: unknown opcode "int"
as: "hello.S", line 23: error: statement syntax
I am not sure how to interpret these errors as I am still trying to learn assembly and have no idea of its syntax in general.
Any help would be appreciated.
Thanks
The more applications I write, more I find out how less I know
