I perused the list archives for all of 2018 and did not see anything current relating to this problem, so if this is a question that has been asked & answered, please feel free to point me at the relevant location to read about what I'm doing incorrectly. =) I'm not at all familiar with Windows & compiling Open Source projects, but I am having no trouble on Linux with OpenSSL + FIPS. On Windows, with Visual Studio 2017 (Community Edition), I am able to compile the FIPS 2.0.16 module and OpenSSL 1.0.2q (NO FIPS) without issue. When I try to compile OpenSSL with the FIPS canister, per the User Guide instructions, I end up with the following error. cl /Fotmp32dll\o_fips.obj -Iinc32 -Itmp32dll /MD /Ox -DOPENSSL_THREADS -DDSO_WIN32 -W3 -Gs0 -Gy -nologo -DOPENSSL_SYSNAME_WIN32 -DWIN32_LEAN_AND_MEAN -DL_ENDIAN -DUNICODE -D_UNICODE -D_CRT_SECURE_NO_DEPRECATE -Ic:\..\openssl-fips/ include -DOPENSSL_USE_APPLINK -I. -DOPENSSL_NO_RC5 -DOPENSSL_NO_MD2 -DOPENSSL_NO _SSL2 -DOPENSSL_NO_KRB5 -DOPENSSL_FIPS -DOPENSSL_NO_JPAKE -DOPENSSL_NO_WEAK_SSL_ CIPHERS -DOPENSSL_NO_STATIC_ENGINE /Zi /Fdtmp32dll/lib -D_WINDLL -DOPENSSL_BUIL D_SHLIBCRYPTO -c .\crypto\o_fips.c o_fips.c .\crypto\o_fips.c(61): fatal error C1083: Cannot open include file: 'openssl/fip s.h': No such file or directory NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2017 \Community\VC\Tools\MSVC\14.16.27023\bin\HostX86\x86\cl.EXE"' : return code '0x2 ' Stop. I am doing the following to compile FIPS: cd c:\path\to\fips-source ms\do_fips no-asm I am doing the following to compile OpenSSL+FIPS (Strawberry Perl installed): cd c:\path\to\openssl-source nmake -f ms\ntdll.mak clean nmake -f ms\nt.mak clean perl Configure VC-WIN64A fips no-asm --with-fipsdir=c:\path\to\fips-source ms\do_win64a no-asm nmake -f ms\ntdll.mak I feel like I'm missing something fundamental here and I know the User Guide says to install the FIPS files in a protected area. However, as I'm just building the source on this device, shouldn't I be able to to do the above and have it work? Any help would be greatly appreciated.
