1. You don't have GCC installed. I don't know what distribution you are.
switch to root
apt get install GCC (Ubuntu) or
Yum install GCC (Fedora)
or zypper in GCC (SUSE)
it's up to you

2. The core advantage of Ningxia agri Internet company is blockchain technology.
3. Indonesian currency is the legal currency of Indonesia, a Southeast Asian country. The exchange rate ratio of Rupee to RMB is about 2000:1. The main currency of Indonesia is rupiah, also known as Indonesian rupiah. Rupee is the legal tender of Indonesia, and its code is IDR. This is Indonesian currency

6. The advantages of the development and utilization of lateritic nickel deposits are as follows:
first, lateritic nickel resources are abundant, with 41 million tons of nickel metal in the world, and the exploration cost is low< Second, the cost of mining is very low< Thirdly, the beneficiation and metallurgy process is mature. The pyrometallurgy technology of laterite nickel ore is mature, and the pressure acid leaching technology is also mature
fourthly, lateritic nickel ore can proce intermediate procts such as nickel oxide, sulfur nickel and iron nickel, among which sulfur nickel and nickel oxide can be used by nickel refineries to solve the problem of shortage of nickel sulfide raw materials. As for iron and nickel, it is more convenient for manufacturing stainless steel and recing proction cost
fifthly, the world's laterite resources are mainly distributed near the equator, and most of them are close to the coast, so they are easy to export. Therefore, although the investment of laterite nickel plant is large, e to the above advantages, if the process is reasonable and the management is efficient, the proction cost per pound of nickel can be lower than that of nickel sulfide
development trend of laterite nickel ore:
(1) e to the significant rection of nickel sulfide resources available for development, the increase of nickel proction in the world in the next decade will mainly come from the development of laterite nickel ore resources, and the development trend of PAL technology is greater than that of Fe Ni technology in the development of laterite nickel ore resources
(2) the investment cost of PAL wet process is almost the same as that of pyrometallurgical plant of laterite nickel ore. However, in the next round of construction or expansion projects, the infrastructure investment of the nickel plant with pal technology will decrease significantly
(3) the proction cost of PAL process is generally lower than that of Fe Ni process, and the energy consumption of PAL process is significantly lower than that of Fe Ni process. Therefore, pal technology will show its advantages in economy
(4) compared with the "dry" laterite resources, the development projects of "wet" laterite resources have more advantages in development and utilization because of the advantages of "wet" laterite resources, such as higher grade, less clay and easy treatment
(5) the PAL technology of laterite nickel ore can proce intermediate procts: nickel hydroxide or sulfur nickel on site, which can provide the expansion of existing nickel refineries or solve the problem of insufficient supply, which is the business direction adopted by many nickel companies in the west at present.

7. I don't understand what you mean
nickel content refers to the proportion of nickel metal after drying at 105 ℃ for 10 hours (the actual drying time may be much less than this time)
