Detecting Compilation Errors in Busybox Configurations

[Christian Kästner]

Hi,

one more issue recently introduced in archival/tar.c regarding variable 
zipMode: undeclared identify if compiled without SEAMLESS_COMPRESSION


(my tool reports the condition
((!def(CONFIG_FEATURE_SEAMLESS_GZ)&!def(CONFIG_FEATURE_SEAMLESS_Z)&def(CONFIG_LONG_OPTS)&!def(CONFIG_FEATURE_SEAMLESS_BZ2)&!def(CONFIG_FEATURE_TAR_CREATE)&!def(CONFIG_FEATURE_SEAMLESS_XZ)&!def(CONFIG_FEATURE_SEAMLESS_LZMA))|(!def(CONFIG_FEATURE_SEAMLESS_GZ)&!def(CONFIG_FEATURE_SEAMLESS_Z)&!def(CONFIG_FEATURE_SEAMLESS_BZ2)&!def(CONFIG_FEATURE_TAR_CREATE)&!def(CONFIG_FEATURE_SEAMLESS_XZ)&(!def(CONFIG_FEATURE_TAR_LONG_OPTIONS)|def(CONFIG_FEATURE_GETOPT_LONG))&!def(CONFIG_FEATURE_SEAMLESS_LZMA)&!def(CONFIG_LONG_OPTS)))
for the error, but it's easy to reproduce by compiling allnoconfig while 
enabling only CONFIG_TAR)




Best regards,
Christian
PS: The problem in miscutils/nandwrite.c below still gets reported.
