When trying to build the Android app, I'm able to successfully set up the chroot, and enter it. Once I am inside, as the user "builder" I get a failure on the second step of the installation process "In the chroot, run standalone/android/install-haskell-packages". When I run this command, I get the following error: cbits/cryptonite_rdrand.c: In function ‘cryptonite_get_rand_bytes’: cbits/cryptonite_rdrand.c:63:2: error: inconsistent operand constraints in an ‘asm’ asm(".byte 0x48,0x0f,0xc7,0xf0; setc %1" \ ^ cbits/cryptonite_rdrand.c:78:3: note: in expansion of macro ‘inline_rdrand_rax’ inline_rdrand_rax(tmp, ok); ^ cbits/cryptonite_rdrand.c:63:2: error: inconsistent operand constraints in an ‘asm’ asm(".byte 0x48,0x0f,0xc7,0xf0; setc %1" \ ^ cbits/cryptonite_rdrand.c:87:3: note: in expansion of macro ‘inline_rdrand_rax’ inline_rdrand_rax(tmp, ok); ^ cbits/cryptonite_rdrand.c:63:2: error: inconsistent operand constraints in an ‘asm’ asm(".byte 0x48,0x0f,0xc7,0xf0; setc %1" \ ^ cbits/cryptonite_rdrand.c:87:3: note: in expansion of macro ‘inline_rdrand_rax’ inline_rdrand_rax(tmp, ok); ^ cbits/cryptonite_rdrand.c:63:2: error: inconsistent operand constraints in an ‘asm’ asm(".byte 0x48,0x0f,0xc7,0xf0; setc %1" \ ^ cbits/cryptonite_rdrand.c:94:3: note: in expansion of macro ‘inline_rdrand_rax’ inline_rdrand_rax(tmp, ok); ^ cabal: Error: some packages failed to install: cryptonite-0.16 failed during the building phase. The exception was: ExitFailure 1 So, there is a problem with building the haskell package "cryptonite-0.16". I also get this output a little further up: Failed to install cryptonite-0.16 Build log ( /home/builder/.cabal/logs/cryptonite-0.16.log ): Warning: cryptonite.cabal: Unknown fields: extra-doc-files (line 37) Fields allowed in this section: name, version, cabal-version, build-type, license, license-file, copyright, maintainer, build-depends, stability, homepage, package-url, bug-reports, synopsis, description, category, author, tested-with, data-files, data-dir, extra-source-files, extra-tmp-files So perhaps that is helpful as well. If anyone has any guidance on how to move beyond this or what needs to be changed, I'd appreciate it! Thanks!
