fix build failed on macos

[leleliu008]

close #203

[leleliu008]

echo -e is not portable. some shell not support this argument.

I would not do this. the .lo file is needed to build the library in lrzip 0.641. Perhaps the cat command could be used. Mac users have compiled lrzip successfully. The echo -e command allows escape characters to print to the output. Perhaps try hard coding /usr/bin/echo since shells are not guaranteed to work the same way as the bin.

ASM/x86 have been handled in C submodule.

[pete4abw]

IDK who added this. But if you do this, you'll have to make sure there is nothing in the x86 dir that IS needed.

[leleliu008]

I just wanna successfully build lrzip 0.641. I don't wanna change too much.

[pete4abw]

Generally, people who package lrzip would tailor its settings. The changes you suggest are not appropriate for a wide audience. I would make this a local change for your fork.

the macOS user can't build lrzip 0.641 successfully.
Homebrew/homebrew-core#71422
HomeBrew still using lrzip 0.631 due to this problem.

Just do ./configure --disable-asm. Removing @echo will break things. I have resolved other homebrew issues although I don't know anything about that build system. Your patch will not solve your issue. --disable-asm will.

[leleliu008]

I'm not just removing @echo but replacing @echo with printf , you should see Files changed. this patch have been tested on my local mac, It can be successfully built.

Glad it works for you. Certain shells do not support all echo commands. /usr/bin/echo should work as advertised. I don't think I will adopt it. Better solution is to not have to kludge it at all. But automake assembly support does not support pure asm files. That is where I will put my effort. Removing the SUBDIRS could affect how make dist operates.
