Description:
XORSearch is a program to search for a given string in an XOR, ROL, ROT or SHIFT
encoded binary file. An XOR encoded binary file is a file where some (or all)
bytes have been XORed with a constant value (the key). A ROL (or ROR) encoded
file has its bytes rotated by a certain number of bits (the key). A ROT encoded
file has its alphabetic characters (A-Z and a-z) rotated by a certain number
of positions. A SHIFT encoded file has its bytes shifted left by a certain
number of bits (the key): all bits of the first byte shift left, the MSB
of the second byte becomes the LSB of the first byte, all bits of the second
byte shift left, … XOR and ROL/ROR encoding is used by malware programmers
to obfuscate strings like URLs.

Comment 2 fszymanski 2016-07-07 13:33:09 UTC 
Hi,

I have a few suggestions.

1) You need to list a BuildRequires against gcc in your spec file.
See: https://fedoraproject.org/wiki/Packaging:C_and_C%2B%2B

2) This is enough:
%setup -q -c

3) The -trigraphs option converts ??) to ] and this is not what you want here.
Instead use -Wno-trigraphs to suppress the trigraph warnings.
See: https://gcc.gnu.org/onlinedocs/gcc/Preprocessor-Options.html
Consider also using the optimization flags.
Example:

%build
gcc $RPM_OPT_FLAGS -Wno-trigraphs XORSearch.c -o %{name}

4) You don't need this:
rm -rf $RPM_BUILD_ROOT

5) And finally for the convenience you could define a %{pkgver} macro.
This way you are changing only the version.
Example:

%define pkgver %(echo %{version} | sed 's/\\./_/g')

Group → not necessary
BuildRoot → should not be used
[https://fedoraproject.org/wiki/Packaging:Guidelines#Tags_and_Sections,
https://fedoraproject.org/wiki/EPEL:Packaging#Previously_required_boilerplate]

%setup -q -c
%patch0 -p 1 -b .cosmetics
→ %autosetup -p1
(unless you needs the backup file...)

+ license is acceptable (PD)
+ license is specified correctly
+ package name is OK
+ builds and installs
+ provides/requires look OK
+ latest version

Package is APPROVED.
