Solution

The problem is the end of life of ACMEv1

The only solution is to upgrade certbot, in case of Debian 8, you need to upgrade to Debian 9 in order to get a recent enough version of certbot.

$ sudo apt-get install certbot

'C:/dev/react-ts/node_modules/i18next-intervalplural-postprocessor/index.js' implicitly has an 'any' type.
Try `npm install @types/i18next-intervalplural-postprocessor` if it exists or add a new declaration (.d.ts) file containing `declare module 'i18next-intervalplural-postprocessor';` TS7016

2 | import i18nLib, { InitOptions } from 'i18next';
3 | import LanguageDetector from 'i18next-browser-languagedetector';
> 4 | import intervalPlural from 'i18next-intervalplural-postprocessor';

Solution

Create the type file manually. There is no @types npm module to install for this one.

Create js/@types/index.js and type in it :

declare module 'i18next-intervalplural-postprocessor';

valgrind: failed to start tool 'memcheck' for platform 'amd64-linux': No such file or directory

Solution

This occurs when you have built locally with "make" but without "make install"

The solution is to export VALGRIND_LIB to the full path of the .in_place folder :

$ export VALGRIND_LIB=/home/flemieux/valgrind/.in_place

Troubleshooting

Problem:

/usr/bin/ld: skipping incompatible /home/frank/kraken/vfcore/protobuf/arch/CentOS7-linux-i686/protobuf-2.4.1/stage/lib/libprotobuf.a when searching for -lprotobuf

Solution:

The library is 32-bit, but the node.js addon build is 64-bit.

You can check the architecture of your .a with :

objdump -f /home/frank/protobuf/arch/CentOS7-linux-i686/protobuf-2.4.1/stage/lib/libprotobuf.a | grep architecture

architecture: i386, flags 0x00000011:
architecture: i386, flags 0x00000010:
architecture: i386, flags 0x00000011:
architecture: i386, flags 0x00000011:
architecture: i386, flags 0x00000011:
(...)

So the solution is to change the include dir to
"-L/home/frank/protobuf/arch/CentOS7-linux-x86_64/protobuf-2.4.1/stage/lib",

Problem :

/usr/bin/ld: /home/frank/kraken/vfcore/protobuf/arch/CentOS7-linux-x86_64/protobuf-2.4.1/stage/lib/libprotobuf.a(common.o): relocation R_X86_64_32S against symbol `_ZTVN6google8protobuf7ClosureE' can not be used when making a shared object; recompile with -fPIC

Solution

Your config.h from the configure step probably has

/* Define to rpl_malloc if the replacement function should be used. */
#define malloc rpl_malloc

Just comment out that line, and recompile "make" or "make -j1"

Successfull Compilation!! Yayy!!
